I had the Version from June-1995 and want to write the latest from Nov-1995, but I'm not able to program the ROM correctly: Program SST PH29EE010 EEPROM Bios with TL866II Plus

I tried to program this EEPROM (Gigabyte GA-486AM/S) but it always stops the execution immediately: APP Version : 12.60 Model : TL866II Plus Device : SST39SF010A Pins Detected Passed! Erase ...Succeeded. Time : 0.407 S Programming FLASH ... ERROR! Address:0x000000 Buffer Data:0x0025 Verify:0x009A …

You have to select SST39SF010A in Xgpro (TL866II Plus).

Thank you @kixs, but first I need to update my BIOS. Do you know how can I program that SST PH29EE010 chip with the TL866II PLUS, or do I need another programmer? Thx

For others: Gigabyte GA-486am/s

It's a rev 2.21 but which jumper settings do I need for that CPU? (User Manual has no information about that)

Hello! I just want to ask which settings on my board are needed to setup the X5 CPU correctly? Currently I have an Intel DX4-100 and the User manual give me no information about the X5 (but I should be possible because I have seen already this board / CPU combination)?! Thank you very much.

I ordered now the PS2TOSERIAL adapter from Matze (https://www.serdashop.com/PS2TOSERIAL).

OK, but which solution do you use then? (I don't want to use old Bus mices)

(or do you recommend another one e.g. a PCI card with PS/2 connectors?) => for a 486 PC (Gigabyte ga486am/s …

I ordered now the Hercules Terminator 3D/DX S3 Virge/DX PCI 4MB! We will see 😉 Thx

On another page (amoretro.de) the author suggested to get a S3 Trio64 with 4MB RAM for better screen resolutions on windows. What do you think? Cards with 4 MB are also hard to find on e.g. ebay.

Thanks for the numerous responses and tips. Since I'm not aiming for Quake I think I will stick to the Trio64 in the meantime (Doom should run fine?).

Thx @jakethompson1, but why no Voodoo 1 (1996) for 3D and a e.g. S3 Trio64 for 2D (loop cable)? Should I run MS-DOS 6.22 or Win95?

Hello! What PCI video card do you suggest for this system: Gigabyte GA486AM/S AMD-X5-133 ADZ CPU Am5X86-P75 230W Power Supply 8MB RAM => will upgrade it to 64MB? Sound-Blaster 16 CT2290 OPL (ISA) 3Com EtherLink III 3C509-COMBO (ISA) It should have the best possible 2D/3D capabilities.

I had my Gigabyte GA-486 AM/S up and running and used a peltier element with a capable version of the 5x86. It's unfortunately not 100% stable which I can maybe change by hopping onto another board with a variable voltage regulator. Nonetheless a nice experiment. And which Graphic Card is in use …

I my case (386SX Laptop) the RTC chip (DS12885S) on the nwX287 replacement was faulty. After replacing it with another one the error was gone.
