Bios update failed on a chaintech 6btm, any helpers?

Postby renz20003 » 2019-3-17 @ 11:43

While flashing it started failing writing blocks, I suspect a bad floppy disk. Didn’t find any jumper settings to get into a recovery mode. Anyone have any ideas on if this can be saved?

When the motherboard BIOS is corrupted to the point that the board no longer boots up, you need to remove the BIOS chip and use another device to rewrite the BIOS EEPROM properly.
There are several devices that be used to rewrite a BIOS EEPROM:
- External EEPROM programmer.
- Hot Flashing using another motherboard with the same BIOS socket: Guide. Warning: Be careful with this.
- Use a Network Card with EEPROM socket on another computer. Never tried this myself..

Software for DOS: Uniflash

It does try to access the floppy before it starts freaking out, I’ve read that some AMI BIOS could be reflashed in that case.

Thanks for the info

You're welcome.

I don't know what reflagging is..

I hotflashed some BIOS chips yesterday. One other tip I can give, is to put a bit of ribbon cable (like 7cm in length) underneath the EEPROM before inserting it into the socket. This way it is easy to remove an EEPROM.

That is the most proper way. But I don't have any such device myself.

I think you need a minimum of 10 posts.

I can't figure out how to use that site to download, it wants me to buy some program. With some googling I found 6btm0505.bin as the most recent so I downloaded and will burn that for you.

I saw your pm but it will not let me reply, either need more posts or the mods haven’t enabled it yet

Possible word of caution - do you know your board revision as some of the later bioses don't support Coppermine on early revisions. According to Chaintech it looks like anything below revision E is out for Coppermine support with the later bioses and some at E and above are only with specific board IC support

Intel Coppermine CPU supported model listing

This table just offer old chipset for Coppermine CPU support.

6BTM - E / F / G / H / J / K version full support, L / M / N version support only with HIP6004BCB ( U9 )

Also, there is a later bios revision https://web.archive.org/web/20010305080217/http://www.chaintechusa.com/BIOS/686/6BTM0817.EXE

08/17/00
Please don't use Coppermine CPU after update this BIOS on C/D version !
Changes made in this update:
•Support EON 29f002nt flash ROM.
•Update micro code.
