I upgraded from a Biostar VX chipset motherboard with a Winchip 200 MHz CPU to a P55T2P4 with a K6-2+ 475 @ 500 MHz in the spring of 2001 after reading "Oldie Tuning" on Tom's Hardware. Jan's BIOS wasn't yet available, so the board reported it as an unknown CPU, and my hard drive was a thirty gigabyte Maxtor ATA66 so that wasn't an issue. It was the cheapest way I could upgrade since it meant I could continue to use use my AT case and 72 pin SIMM memory. I also upgraded to a sixteen megabyte (maybe it was actually 32 megabytes?) video card. I later flashed Jan's BIOS, and used it to build a computer for my mother.
Great tutorial video. I have both versions of this motherboard and I want to flash MR. BIOS that I found on multiple websites. Have you ever attempted flashing MR. BIOS? What made you pick UniFlash instead of pflash.exe or aflash.exe supplied by ASUS? I had so far no luck with original flushing software that came with MR. BIOS. Do you think I could use UniFlash or pflash.exe from ASUS to load MR. BIOS? I posted similar question on Vogons forum, but so far I got no replies. I would appreciate your opinions.
I looked for the 'safest' way to update the BIOS with the unofficial version (support for additional CPUs, larger HDDs, Y2K fix, etc.). I have not looked into MR. BIOS. But during my research, I came across multiple posts that the official BIOS flashing tool from ASUS could cause issues - even with the official BIOS releases you can download from ASUS. I basically wanted to make sure that I won't brick the board due to a failed BIOS flash. Uniflash has a readme included that actually states to support the ASUS P55-T2P4. I am curious - why would you use MR. BIOS?
@@bitsundbolts Once again, thank you for your video. I have listened to your suggestions and used Uniflash to upgrade the board to the latest (302) Award as well as MR BIOS with no problems whatsoever. MR BIOS, although might seem very primitive compared to ordinary AMI or Award, nevertheless, it was an extra 3rd party upgrade and according to many, very fine tuned one (better memory timings, etc.). Few features I like the most are: - almost instant warm reboot, - you can enter BIOS setup without reboot with Ctrl-Alt-Esc - you can reboot with a boot drive of choice with Ctrl-Alt-Enter - you can enable/disable external cache with Ctrl-Alt-"+" or "-" also without entering BIOS. Anyway... think of it as an AMG version of a Mercedes-Benz.
Danke für die Anleitung, werde bei meinem T2P4 von 0207 auch auf das gemoddete BIOS wechseln wegen der HDD Unterstützung. Welches Testprogramm nutzt Du für den Y2K Bug und die Systemkomponenten am Ende?
I updated the link with the latest backup using wayback machine. I guess we are loosing data. Maybe it would be good to get a backup of this collection before it is gone.
@@bitsundbolts You have a great BIOS version as long as you have the ability to change the IRQ of the serial port. If you still have the motherboard, I hope you try changing the IRQ for the serial port, because it is a wonderful and rare possibility. Thank you so much
On your bios boot 06:36 i see pci serial bus controller with irq 12. Do you have a PCI serial card? Or its an extension bios on the main bios? Thank you
No, this must be the onboard serial. I also do not use any extension BIOS, just the regular board BIOS (which is modified to fix a few bugs, but I don't think it has any extensions that would make the serial bus controller pop up in this screen).
32MB + 64MB (wobei 1MB = 1024KB). Dadurch kommt man dann auf die Zahl auf dem Boot-Screen. Sind aber 96MB. Leider fehlen mir funktionierende Speichermodule um 128MB oder mehr zu konfigurieren
Hello, I have version 0207 official version for this mobo, ( not the modded one,) the thing is that it does see a 20GB HDD I have, but when I am using, it freezez and unfreezes for 1 second, randomly at about 15 seconds or less continuosly, I will try to add the modded bios maybe it will help with my problem, I think the problem could be the bios cause when I use my 1.3GB HDD it never does the freeze unfreeze thing, I will post later what hard drive does my original 0207 (1998 date) version of bios read but has that problem :D
Update: I did the bios patch and works perfectly now, no more freeze / unfreeze, but i also upgraded to a 60gb HDD :) thanks a bunch for the tutorial, it really fixed what I was looking for! Subscribed!

Great camerawork and lighting. Thanks for a walkthrough of topics regarding this motherboard. I have the same in a retro-computer build.
Thanks a lot for this! Worked without issue, I was having that same 8GB limit.
You're welcome! Happy to hear that it worked without issues

Ich benutze ein Tool mit dem Namen SpeedSys 4.78. Dieses Tool ist Teil des DOS Benchmark Pack von Phil's Computer Lab.
@@bitsundbolts Danke für die fixe Antwort! Dann teste ich das mal aus :)
back in the time I used to use biossavior.... let you search what it was, I wrote an review of it in 2001.... sad, i'am becoming old now :D
Hola desde Argentina buenos Aires
Curiously there's not a bios for gigabyte ga-686lx4 patched for hdd >40 gb
Geteilt ;)
seems like the bios mods link is broken, wayback machine still has it though
I updated the link with the latest backup using wayback machine. I guess we are loosing data. Maybe it would be good to get a backup of this collection before it is gone.
Thank you
With this update can you change the IRQ nember of serial ports?
I am not 100% sure, but I think there is an option in the BIOS (a whole page) where you can reassign IRQs.
@@bitsundbolts You have a great BIOS version as long as you have the ability to change the IRQ of the serial port. If you still have the motherboard, I hope you try changing the IRQ for the serial port, because it is a wonderful and rare possibility. Thank you so much

@@bitsundbolts I think the tow port share the same IRQ and the ports get initialized from an bios extension on the main bios file.
That's how it displays the USB controller.
Mit welcher RAM Konfiguration kommst du auf 98 MB laut Start Screen ?
32MB + 64MB (wobei 1MB = 1024KB). Dadurch kommt man dann auf die Zahl auf dem Boot-Screen. Sind aber 96MB. Leider fehlen mir funktionierende Speichermodule um 128MB oder mehr zu konfigurieren

Im Moment leider nicht. Werde bald in ein anderes Land ziehen und ziemlich wenig Zeit haben. Trotzdem Danke!
