It should presumably match this:
BIOS info: 01/09/2000-i440BX-W977-62400000C-EC
Sure enough, it does say "i440BX-W977-62400000C-EC" on post. Since it does say that do you believe flashing it with a bios for a "ATC6240M V3: PCB rev R06" would work rather than brick it?
Thank you for pointing me in the right direction. Also thank you for the information about A-trend in general. It totally makes sense they would use reuse boards and use stickers to cover up model numbers.
That string does point to that particular version board, though I would come up with a backup plan in any case something goes wrong.
BIOS updates are located here: http://www.win3x.org/uh19/motherboards/7078
ATC-6240BX BIOS Released Note.doc: with the only BIOS note for rev R06 preserved.
This BIOS version 3.0r05 support for :
1. new Celeron ( so far 766 MHZ above )
2. Pentium III ( Coppermine ) up to 850 MHZ .
3. implement Win ME & Win 2000 Hibernate feature .
4. VIA Cyrix III CPU
Also I JUST noticed this note on the page I linked:
"backside of the motherboard near the DIMM slots gives PCB rev, only R06 has Coppermine support"
I wonder if it says some form of "R06" on the bottom of the board? No one person would normally think to take a photo of the bottom side of the board. However, I checked my own Atrend 6240M board, and sure enough, "391-6355-C00R03" was printed on the silkscreen. So mine is a rev R03 board. My board is a green color, however.
I'll also have to correct my own statement on the board layout, as I just have run into a picture of a gold version of the ATC-6240 with the earlier board layout that 6240M R01-R03 and 6240V-00 uses, possibly rev R05. (Ironically, they were adding stickers on those boards for the ATC-6240v-00.) So, only ATC-6240M V3: rev R06 and ATC-6240V-01 use the same board layout. Insane. The 6240M v2 board entry will need a photo change on win3x/Ultimate Hardware 2019, as it is the wrong photo for it.
It also seems I will have to update my own ATC-6240 page with this info.
Computer in my collection that had too much work done is... Compaq Armada 1573DM!
