First, you have to check your diagnosis was exact. It may not be a BIOS problem. If you are experienced PC user, you can confirm it with replacing each parts.

SST 49LF040 and SST 49LF040B is fully compatible flashrom. So, if new 49LF040B was writed with a correct BIOS, the motherboard must work. Sometimes socket and flashrom pins shape can be changed or polluted. And it can make pin-contact bad. Check first these. And did you request the 49LF040B with cor...

Making a Flashing tool requests a many knowledge. 1. PC and BUS structure. 2. CPU protected mode. 3. Undestanding about address translation(=#CS) of each chipset. 4. Each register function of each chipset. 5. Flashrom programming sequence. 6. Assembly(even inline) and one more programming language. ...

Pull-out the jumper. (not 1-2 or 2-3) Then, retry update with floppy. I recently replaced an original pata HD in a profile 5 with a 250Gb SATA. The machine only recognized the new drive as 128Gb so I decided to flash to the latest version of the BIOS to see if that would help. BIG MISTAKE..... the m...

Microcode update is not BIOS execution code or CPU detection data.
You must modify a execution code of CPU detection and initialization.

Look for a BIOS flashrom.
If you can't find a flashrom easily, there is no way.

Thank you.

Check your floppy drive. If floppy drive doesn't work(rotate with noise and flashing a front LED), this BIOS doesn't support recovery mode. And K8 are useing a LPC flashrom And LPC flashrom is little unique. Check your flashrom model name. It may be one of 49LFxxx, 39Vxxx or 49Vxxx. They don't have ...

Search "ISA PINOUT" at Google.
A18 is one of ISA pinout.

Anyway, I would try but how do I find A18 pin on the socket?

Hot-Flashing or Flash-ROM-Programming is available. The flashrom is inserted in socket under memory socket. You can find many topic about Hot-Flashing in this forum. Also, some flash rom programmer is very cheap($20,include postage to world wide). You can find NANO BIOS Programmer at Google. *CAUTIO...

You have to understand about address translation of ISA interface. And Gigabyte GA-7VAX1394-A doesn't have visible ISA pinout(=a18 pin). So you can't use this M/B. And uniflash will erase all data in 39SF040 before write. So, previous programming part will be erase. You can resolve the error with pu...

Yes, 3V chip will die within a couple of days(or second if bad luck).

It will work or 3v chips will get fired?
