I have a M919 v3.4 B/F and it's eprom says: "M919 3-6, 9622 C65SG" under the AMIbios label (# B141873). The flash jumper JP2 is set for 12v on my board, your SST29EE010 runs on 5v as do many but may need 12v to actually program it (will have to read the datasheet). Sorry but I have no need to flash the rom but will check it with Uniflash v1.4 to see if it can detect the eeprom type. Will take a while as the board was just pulled out of antistatic bag because it was in storage.

Unknown type off the board ! Ok so put rom into a trusted 3com 905tx nic on another motherboard (to see if the 919 board is write protecting) and got same Unknown Type.
Maybe one of the others can help...

original M919 bios chips with "M919..." print are not flashable.

I could flash the BIOS of my original M919 v3.4B/F just fine. Also, I've never seen an M919 with a BIOS chip that says "M919" on it. If it does, it's probably *not* original. The BIOS should be a flash chip (EEPROM) with an ordinary "AMIBIOS" sticker on it.

Just like they liked to remark chipsets, PCChips loved to remark bios chips. If you have an EPROM programmer like a TL866, you may be able to find out which chip it is : select a similar chip from the era, then there's a function to get the chip's id. If you find it, please send it to me.

I need to replace my aged CT's clone card (it will not work with 28pin chips), do you have a suggestion of where to get a real TL866 for the lowest price ?

Here is a pic of the BIOS on my board, yes very odd to not have regular eeprom manufacture printing. The AMI sticker covered most of the odd M919 printing.

I don't really have suggestions. I just bought mine on eBay.

I can check when Im back home via my programmer,what that chip really is.

i wasnt able to figure it out and i replaced it with another and flashed it with my tl-866.

If you need a chip flashed, let me know. I can do it for you

I have found out,that I have few brand new SST 29EE010, so made a hotflash with the last update and works like a charm.

so that SST29EE010 worked in the board no issues same pin out ?

yes, they both have the same JEDEC pinout.
