this is such a nice xt-ide board it looks really professionally made i see the "rear of pc" markings on the board can't wait to try it out this weekend.
Some of the boots were sped up (2x -3x) just to keep things moving but yes.. the full 256 of L2 makes it peppy, mine started at 64 and that was a bit slow.
Thanks for mentioning ;) Would be nice to see the output of your attempt with the network card. What it does is just making the ROM accessible at particular address, basically the same thing what you've made with the custom ROM card. If you shadow the address, the ROM will be just loaded into the memory and the network card will be even out of the equation completely. If that didn't work, most likely the addresses which have been chosen for the try with the network card were conflicting with something. Anyway, congratulations to your success! Glad it works now as expected.
Thank you so much for the wisdom you share, you are such a positive influence to me and the retro community. I will definitely retry that Network card in the Fortiva, but this time with an M27C128, I did try several addresses but nothing changed the results. I was assuming it was due to the W27C512 chip I used. I think I saw you using an m27c512 in your video so that's why I gave it a shot. What was peculiar was the four lines it added in the Bios (where it shows the Addresses), as if for each copy of the ROM info I added to make the W27C512 work. Perhaps that was creating a conflict.

I have a 486DX2-80mhz board I got last year (almost to the day, literally) that I've built up. The stock BIOS would not allow me to run a primary partition of over 512meg, no matter what I did. Went with the XT IDE (Board, chip, IDE socket, the whole 9-yards) and I absolutely love it. It's "slow to boot" but gets the job done and works fantastic with the 2Gig CF card I have in it. (Dos 6.22 at that) I initially had problems with having BIOS setup to run too fast for the ISA slot. It was EXTREMELY temperamental when you run too fast. Dropped to PCLK/3 instead of /2 and I haven't had a days worth of problem. Even my Trident card, which I thought had memory problems and characters randomly turning into spaces fixed itself after I slowed things down. This 486 is one of my favourite machines in my collection (And I do have a collection of PC based machines, including Commodore)
This is good to know, I'm checking right now and I can't change any speeds with this terrible Phoenix bios so whatever it's currently running at is clearly working fine. I do intend on using these boards with 386s though that info will come in handy when I try that. Thanks. Hey, I'm curious as to what your 80mhz scores in "System info" do you have Phil's Benchmark?
Just a heads up, though, I had to reflash my XTIDE because this System Info app screwed up huge. I inadvertently went into the disk benchmark (Started typing on the wrong keyboard). It completed once because I was busy typing somewhere else when I realized what I did, and I got a pitiful score from what I remember (I don't remember the numbers) but ran it a second time, this time intentionally, and it went to hell. I ended up having to reflash the XTIDE. Took about an hour to remember my settings, validating the CF was healthy, taking the machine apart to validate dips switches and all that, but yeah... Fortunately, I have all that on my GoTek with a bootable disk image, so I was able to easily get back and going. But, that system information tool (And probably other tools) I won't be stress testing outside normal DOS games. ;)
I’d recommend trying FreeDOS. The current version uses ExFAT, giving you the ability to use much larger volume sizes, while still giving you full DOS compatibility. Granted, I use it in VM DOS machines, but can’t make myself go back to the official. It also has tricks to load more stuff into high memory, meaning the old memory hungry game titles always have enough conventional RAM.
Thanks, I will definitely try that. Now that I can actually use a larger drive. Kinda forgot about FreeDos, appreciate the reminder.

Im not surprised Wiretrap designed that board, he gets around 😆 I would get a "Startech IDE to Sata adapter", google that. Should have a red PCB. They use a Marvel chip unlike the cheap ebay 5USD garbage. The Marvell chip is larger, more pins then my china none working crap adapter. Have not tried them in a 486 BUT they tend to work in 95% of stuff, Master, Slave and CS jumper, up to ATA 133 support and Optical Unit support. One of those might work properly with a SATA drive, I tend to use SSD's, at least they are the best once I tried. May I ask what was the biggest usable size XTIDE would detect for a hard drive? On my slowest 486 I use Dynamic Disk Drive Overlay to get a 20GB IDE drive to work with all its space. Good video!
"May I ask what was the biggest usable size XTIDE would detect for a hard drive?" it add LBA48 translations, which is what modern windows uses so PB's? ... stuff one of these into an 8086 and DIR it up! and wait and wait...
Dude, big fan of yours. Really appreciate all your work. I was able to get an 80Gig drive but the next 120Gig failed I didn't put that into the video. I kinda think it would accept higher than 80gigs but I was testing it for my friend that only uses 1-2 Gig drives. I'll try it with some more 120Gig Plus drives and get back to you.
Good video. It gave me a kick in the pants to finally figure out what is up with the Pentium box I bought last month (sketch voodoo card, LCD unfriendly VGA scan rate in bios).
Did something similar to mah Leading Edge WinPro 486e! Build an XT-IDE with CF card PCB and only populated the XT-IDE BIOS part and yeah, it works nice! Even went as far as configuring XT-IDE for 32bit transfers with a VLB IDE card! ... and went overboard with an Awe32, ISA SCSI (No ROM), VLB IO card, ISA 3com Ethernet, and VLB Cirrus Logic card! what fun it is to see another Leading Edge!
Very interesting. Learned a few things here. I never got a chance to try Necroware's discovery of using an old ISA network card with the ROM socket as I have few kicking around here. I might just try the XT-IDE thing as I have not been successful with SD cards in my older machines, only the compact flash and of course I picked the shitty Sandisk compact flash cards that cannot boot and have to use a boot disk every time with those 2 machines. I have an old Leading Edge 486 under a mountain of computers but it certainly isn't a Fortiva 5000, it's an older blue and red label Leading Edge desktop that never did post and I just squirreled it away for later.........15 years ago.
I'm using the cheapest possible CF and SD cards with the Fortiva, that doesn't seem to stop XT-IDE working like a charm. I would definitely recommend try it out, I can't get over how effective it is on a machine I was about to toss on a pile and probably neglect for 15years as well. I'd suggest using the M27C128 it makes the programming very simple. I really get a kick out of using SD cards on these old machines, it gives them a new life. Maybe it's time to do some excavation and dust off that Leading Edge machine, they were built to last so much longer than anyone could have imagined back then.
Thanks for video with explaining. I have made expensive XT-IDE with more IC's with IDE socket. Some logical IC's from China are in bad condition, and little pain.. This Lite XT-IDE card are cheap and useful. I will use this card on some boards, when cannot modify bios. Some problems with notebooks 286/386/486, when problem add CF parameters. For Your PC 486, need add old HDD, only power cable, for drive noise :) or make arduino, HDD head moving sound.
It goes together in minutes, really is an elegant solution. I've seen those addons that make the Hard drive clicking sound but I'm fine with just the LED flashing, I can dig why people want to restore that sound but I love the silence personally.
It's pretty convenient, but on this machine win3.1 had a problem with the mouse, otherwise normally it works with everything else. I looked on the back of it, it's a "Data 911 MDS2000 Mobile Data System". I got it with a lot of computer stuff years ago. The cable splits into 2 PS/2 connectors.
I love the sounds of old hard drives... and to me, a loud fan is a working one. I know, I'm weird :D I have to wonder if something doofy is going on with your IDE drive controller... I've never had trouble with IDE-to-CF or IDE-to-SD. As an aside, Noctua isn't lying about their fans being so much quieter... you'll pay for it, though.
Agreed, I've never had trouble with IDE-CF/SD either but this version of the Phoenix Bios is impossible to deal with, in Necroware's video he was using the same Bios with similar issues and my friend on VCF, so I know it's not just my machine. I sense you don't trust the Noctua air output compared to regular fans?
So was the ultimate goal to get LBA support? Have you written more than 528 MB of data to the drive to make sure there are no further corruption issues?
@@esc2dos got it! Another concept that would be interesting to try is a MR BIOS that is compatible with your motherboard's chipset. I have a link to a spreadsheet if you want to try it. I've converted a few of my systems to have LBA BIOS support that way. And it would be a fun video idea too! I did run into a case where I had a goofy controller card and ended up doing exactly what you did here as well! I've got a few threads on Twitter/X that talk about it!

@@stephenjourdain1842 It's NOT emulated. The Vortex86 is a real chip, x86 ISA compatible. As for the Lama ITX, guess it's appealing to anyone that "needs" perfect sound options, but other than that... price is a killer. The Vortex86 SOC will give you a really cheap x86 compatible mini-pc out of the box (like the EBOX stuff by DMP), but adding all the "vintage extras" drives the price up. At which point, if you can live with "less than perfect sound" BOSBOX/86box/PCem are reasonable options, and if you need more than P233MMX power, XP era boxes can be made for a song, just pick any 2nd/3rd gen i3/5 from the dumpster bin.
I used a xt-ide in my 486 so it could boot from modern higher capacity IDE drives (ones that still worked lol), good solution till i got my scsi-sd card adapter (the 486 i had, cam with built in scsi, ide, lan) which allowed me to boot images
@@esc2dos Dynamic Drive Overlays - Commonly used to push past the CHS barriers (to a point) - In some situations, you can put any CHS parameters into BIOS and let the DDO do the rest. In all cases, the HDD has to be recognized by the BIOS - I remember trying 30 different parameters on my non-CHS editable NCR back in the day until I got one that didn't throw an error, and I was able to use a 212 Mb hard disk on a 20 Mhz 1989 386 ;)
they are disk images of hard drives, i remember what it was called, BlueSCSI 2. you are able to assign different images to different SCSI bus channels as well as mounting an iso as a CDRom IIRC
Try different SATA to IDE adapters. I found that some work on certain machines, others on different machines, and some don't work at all. Controller chip versions etc differ so it's a trial and error process.
Ya, that's kinda what I assumed. Really is a hit and miss with these old machines regarding compatibility. If I get another SATA adapter I'll make an update. Thanks.
I'd suggest driving at 88 mph and returning to the 90s to get a few Compaq Presarios .. come to think of it while you're there, could you find me an extra Fortiva 5000
@@esc2dos yeah, Daewoo had a good reputation in many things. I do own two daewoo cars (i owned quite a few of them) and i also own daewoo appliances like fridge, microwave, washingmachine. everything works for years now without issues. Daewoo collapsed because of bad leadership... not because products were that bad. they are actually quite decent for that price.
@@esc2dos just fyi, Daewoo was first to sell cars trough it's own dealership, back in 1990's when other car manufacturers sold cars to random dealers who sold them with profit to customer. Also Daewoo was first to introduce 3 year warranty that covered parts and labor, also was first to give you a spare/courtesy car while your was being serviced. No other car manufacturer was doing that in the 90's afaik. oh and last thing not many people know, Daewoo worked with Porsche on many of Daewoo's cars and also on their own straight six cylinder engine. Also Lotus was involved during development of Leganza to design and tune it's suspension.
It won't, I have lots of HASL ISA cards that I plugged hundreds of times on my motherboards and everything is fine. Sure, the ENIG ones are better, but the HASL cards and the slots will be fine.
@@BaguetesGarage Even ENIG is not enough. You never bothered to look the connectors in the slot up close.The usual answer from people who don't know. All professionally made cards use hard gold plating. ISA,, VLB, PCI, AGP, PCIe and all cartrdges for vintage video game and 8 bit computers have hard gold plating. Incompatible metals in contact for more than a few days will start galvanic corrosion and then after less than a year you need to replace the connector on a board of a 20-30 year old computer as the contacts become resistive.
@@esc2dos The effects usually take more than a year to show but by then it is too late and you've caused damage to a historical machine. Your card is aimed at PCs that are decades old. I make cartridges for the C64 and VIC-20 which are around 40 years old. Many people in the Commodore 8-bit community made the same mistake and still do with disatrous consequences for the cartridge port connectors. This is insidious because the harm is very slow to become visible unless you use a microscope.
@@francoisleveille409 Good to know, but if I do destroy my IDE port because I cheaped out on the PCBs I'll just solder a new one in. I'll leave it in the same slot to be safe. I appreciate the warning.
@@BaguetesGaragethe problem this solves is that the IDE chips are more-or-less fine, but the BIOS software that DOS uses to drive them is total crap. The XT-IDE BIOS on this card hooks in new code that is totally up for dealing with almost anything you can put on IDE.
As others have already explained, this board has one IDE and a Floppy connection. XT-Ide will work in tandem with Controller cards as well, I'm going to try a VLB card with this machine too.

@@esc2dos Dynamic Drive Overlays - Commonly used to push past the CHS barriers (to a point) - In some situations, you can put any CHS parameters into BIOS and let the DDO do the rest.
In all cases, the HDD has to be recognized by the BIOS - I remember trying 30 different parameters on my non-CHS editable NCR back in the day until I got one that didn't throw an error, and I was able to use a 212 Mb hard disk on a 20 Mhz 1989 386 ;)
they are disk images of hard drives, i remember what it was called, BlueSCSI 2. you are able to assign different images to different SCSI bus channels as well as mounting an iso as a CDRom IIRC
HASL or ENIG?
HASL with Lead, and thanks for that, I wasn't aware there are options.
Try different SATA to IDE adapters. I found that some work on certain machines, others on different machines, and some don't work at all. Controller chip versions etc differ so it's a trial and error process.
Ya, that's kinda what I assumed. Really is a hit and miss with these old machines regarding compatibility. If I get another SATA adapter I'll make an update. Thanks.
What a conundrum... if I subscribe i'll be the 387th subscriber, losing the 386th sub amount... but moving forward to 486 subs.
For me that's a good problem to have, thanks for your sub. And wouldn't you know it, it's just about to pass 486.
Instructions are unclear... there are no expansion ports on my compaq presario cds 524... someone stole my expansion board 😭💀
I'd suggest driving at 88 mph and returning to the 90s to get a few Compaq Presarios .. come to think of it while you're there, could you find me an extra Fortiva 5000
It's nice, because Leading Edge was owned by Daewoo Group.
Daewoo has a good reputation? I'm curious.
@@esc2dos yeah, Daewoo had a good reputation in many things. I do own two daewoo cars (i owned quite a few of them) and i also own daewoo appliances like fridge, microwave, washingmachine. everything works for years now without issues.
Daewoo collapsed because of bad leadership... not because products were that bad. they are actually quite decent for that price.
@@lordmmx1303 That's awesome. Good to hear. I value your opinion. You know them quite well.
@@esc2dos just fyi, Daewoo was first to sell cars trough it's own dealership, back in 1990's when other car manufacturers sold cars to random dealers who sold them with profit to customer.
Also Daewoo was first to introduce 3 year warranty that covered parts and labor, also was first to give you a spare/courtesy car while your was being serviced. No other car manufacturer was doing that in the 90's afaik.
oh and last thing not many people know, Daewoo worked with Porsche on many of Daewoo's cars and also on their own straight six cylinder engine. Also Lotus was involved during development of Leganza to design and tune it's suspension.
Your PCB has no gold plating on the edge connector so whatever ISA slot you plug that card into is going to be wrecked.
It won't, I have lots of HASL ISA cards that I plugged hundreds of times on my motherboards and everything is fine. Sure, the ENIG ones are better, but the HASL cards and the slots will be fine.
@@BaguetesGarage Even ENIG is not enough.
You never bothered to look the connectors in the slot up close.The usual answer from people who don't know.
All professionally made cards use hard gold plating. ISA,, VLB, PCI, AGP, PCIe and all cartrdges for vintage video game and 8 bit computers have hard gold plating.
Incompatible metals in contact for more than a few days will start galvanic corrosion and then after less than a year you need to replace the connector on a board of a 20-30 year old computer as the contacts become resistive.
@@francoisleveille409 I will check for corrosion as the weeks progress. This is perhaps why these boards are so cheap?
@@esc2dos The effects usually take more than a year to show but by then it is too late and you've caused damage to a historical machine. Your card is aimed at PCs that are decades old.
I make cartridges for the C64 and VIC-20 which are around 40 years old. Many people in the Commodore 8-bit community made the same mistake and still do with disatrous consequences for the cartridge port connectors.
This is insidious because the harm is very slow to become visible unless you use a microscope.
@@francoisleveille409 Good to know, but if I do destroy my IDE port because I cheaped out on the PCBs I'll just solder a new one in. I'll leave it in the same slot to be safe. I appreciate the warning.
What are you plugging the drives into? I dont understand how this is all connected or for as there is no IDE header on the card you made.
This is just a ROM board to load the XT-IDE BIOS ROM into memory, the drives are connected to the IDE controller.
It uses the existing IDE controller - I do the same with my ATIDE ROMS mounted to NIC cards.
@@BaguetesGaragethe problem this solves is that the IDE chips are more-or-less fine, but the BIOS software that DOS uses to drive them is total crap. The XT-IDE BIOS on this card hooks in new code that is totally up for dealing with almost anything you can put on IDE.
I'm so thankful that people understand this stuff so much better than me and can override the original Bios.
As others have already explained, this board has one IDE and a Floppy connection. XT-Ide will work in tandem with Controller cards as well, I'm going to try a VLB card with this machine too.
