Very interesting, that this M321 board has a bios that has M320 in it's bios string. I have a Rev 2.6 board with bios datecode of 06/06/92. I've been trying to make sense of the chipset itself for quite a while: Chipset datasheet for M321 (PC Chips)

Bought Samsung Syncmaster 213T, which is 21.3" 1600x1200 LCD for my retro machines. Perfect 1:2 scaling for 800x600 resolution. For lower resolutions, it just has a buttload of pixels to use, so hopefully a good upgrade over current 1280x1024 19" screen. 😀

Is that a PnP card? I see a bunch of jumpers, but are those only to enable the different CD interfaces? UNISOUND lists support for some of the ESS1688 cards. https://www.vogons.org/viewtopic.php?f=62&t=72553 Unisound tool shows "No PnP sound card detected"... You may try to set BLASTER variable …

@Koveras, you could always try out UNISOUND, which is amazing tool / universal driver. If that works, then you can at least validate that your card works. 😀

Another thing with edit is, you can use today's normal "ctrl + c" and "ctrl + v", instead of some "random" keys i don't even remember any more... Yup, at least those parts are totally fine and have no compatibility issues whatsoever.

Even if you can set up drives with their correct size in bios, that doesn't mean it's going to work. Probably you hit the ~500MB hdd support limit. Either set it to ~500MB drive in bios (CF cards are generally fine with that) or use any kind of bios helpers: XT-IDE (1kB conv. mem consumption), …

Oh, so at least with the help of AMISETUP, there's nothing really to match for me to confirm the chipset? Maybe under diagnostic menu there is something which can give away the chipset the mobo is using. Bios Version: BIOS source: Protected Mode BIOS manufacturer: American Megatrends, INC. BIOS …

Old thread resurrection but PC Chips m321 should be based on 82c391/82c392/82c206 Opti-386WB Chipset, here is the datasheet for future reference. The Bus divider options are clk2in/8 or clk2in/6, so with an am386dx40 (80 Mhz crystal) and the 8 divider the actual isa bus is 10Mhz. Input PIN 14 ( …
