BIOS Updates forum

Hi Rainbow. I don't know either how the BIOS became corrupted, since it worked at first I thought everthing had to be fine. Perhaps AWDFLASH, which froze at the end of the flashing, didn't write the boot block correctly? I don't think I have to hot-flash again, maybe using UniFlash I'll be able to c...

How I did a successful hot flash and brought to life my motherboard (You people helped me, now I shall help the others, so I will tell my story) I am the happy owner of a Soyo motherboard – the 486 PCI/VESA Green Mainboard – 4SA W2/W5. Its chipset is SiS-85C496-497, very stable in my opinion. It ha...

Hi. I tried to use UniFlash to hot flash a chip from a different motherboard and I got the message: Boot block mismatch. Proceed anyway? So I tried to flash it including the boot block, and I got the same message. question: Is this "boot block" the one of the system running currently (of which I hav...

How could I identify the voltage regulator on the motherboard? How can I check it? There is a 4-pins black component where we can read PQ30RV21/SHARP/21/F6. It is screwed into a big heatsink and it is near the voltage-select jumpers. The jumpers are set to 3.45 V, the correct setting for the process...

1) Are these files of any utility?
Why would I use HWINFO GETBIOS for then? It seems kind of useless now...

2) Where on the Internet can we get the original BIOS files? (At Soyo site, there are files only for BIOS upgrades and I guess I need the very first version of the BIOS....)

Exactly that, KachiWachi! I used the HWINFO-486 for DOS and it came with an utilitary called GETBIOS, and this program has saved the two files that I said: E000.ROM and F000.ROM. Does anyone have any clue on how I could flash it back, since it isnt a .BIN file??? (these files doesnt seem to have a s...

Now I've got a new mainboard, a Shuttle HOT-433, and the processor Interl 486-DX4 is running OK on it, at 100 MHz. I guess the processor isnt hurt. The Soyo motherboard is still dead, be with the 486, be with the AMD-586-133MHz. It worked 10 minutes after the flashing, so it suddenly stopped and nev...

I thoght it was worth the risk. And after all, the other program managed to read and sabe the original BIOS program. But now, I confess, I am desolated. The board was a "Soyo 486 PCI/VESA GREEN MAINBOARD" motherboard, and the original BIOS was a Award: Award Modular BIOS v4.50 PG 1984-95 Award Softw...

Surely it was set to 3,45 Volts. The DX4 worked for 8 years without any problem. It was in fact a very stable machine. The DX4 is not a Intel Overdrive chip.

These two files are all I got from the original BIOS. The awdflash didnt manage to get a image from the chip before the flashing, so I used other program which I dont remember the name. By looking at the strings in the file we can see that it has something to do with the BIOS program. So I think I h...

Surely. Both CPUS, the 486 DX4 and the 586-P75 work with 3,45 volts, so that I didnt change this jumper on the motherboard.

And the file that a program read from the BIOS to save the original image: it is a image of the BIOS before the flashing but it doesnt seem to have the same format that a .BIN. In fact, I got two files, called E000 and F000, so I concatenated the two files and called it EF000.BIN. And then I tried t...

So the BIN is not the Bios image?
I have flashed a BIN file to my old Award BIOS with awdflash,
and the motherboard went dead.
The BIN file started with:
%
-h5 (something more and)
original.tmp (and more ASCII).
Was that wise, to flash this file to the chip?

Hi all. This is my first message. I hope someone can help me... I have a "Soyo 486 PCI/VESA GREEN MAINBOARD" motherboard, and the original BIOS was a Award: Award Modular BIOS v4.50 PG 1984-95 Award Software Inc REV WA 09/11/95-SIS-496-497/A/B-2A4IBS29C-00 Award Plug & Play V.1.0 I know it's old but...
