The PCB is identical, only difference is which components are implemented on yours (COAST slot vs soldered PLB cache on the old pic, DS12887 vd DS12885 and a CR-2032 battery etc, white shrouds round the flatcable connectors vs no shrouds). This sort of stuff was configured differently on every run, potentially as requested by individual wholesalers.

fair enough, do old motherboards have chip set drivers?

Just to return to the ID - the POST screen gives it away: PM7600. That makes it an Amptron PM-7600. Which is exactly the same as a PC Chips M507, as PC Chips sold its motherboards under a bewildering array of brand names, including Amptron.

That said, all the important info other than that has already been given. Do note that early So7 boards frequently had VRM sockets, but few actually kept BIOS support long enough to properly cover Pentium MMX CPUs when they finally appeared, so even if you get that VRM, you might still have issues. Most likely just cosmetic ones though (CPU type and speed incorrectly shown), but some boards may fail to boot with unknown CPU.

Indeed, time for http://web.inter.nl.net/hcc/J.Steunebrink/k6plus.htm (User chkcpu)

Thx for the pics.

Okay as hoping there was gonna be a model between the slots… darn.

That does look like the board.

implemented with a coin cell and different rtc though

All hardware requires drivers of some sort. The question is whether those drivers are available and if so whether they are integrated into whatever operating system you are running. This board is a bog-standard i430FX board.

- DOS doesn't have any specific support I'm aware of.
- Windows 98 and later versions of 95 have drivers built in.
- early Win95 needs separate drivers, available here http://vogonsdrivers.com/getfile.php?fileid=1 … menustate=31,29
- Linux has natively supported it since forever.
