I obtained a generic Turbo XT board in a flip-top case recently and I'm trying to figure out the jumper/DIP switch settings for the motherboard, but I don't really know what board it is.
The BIOS stickers say "WASAE CORPORATION TURBO XT MOTHERBOARD" and those are the only branding I can find on the board, it's definitely not anything special as far as boards go but I would like to know how to configure it.
Can you take a picture of the whole board ? Most XT clones with one 8 block switch use same switch settings but not all (have one with 3 x 8 block switches.
A good place to start is with the Typically:
SW1: Normal/test mode
SW2: Math co
SW3 and SW4: memory size.
SW5 and SW6: video adapter/monitor type.
SW7 and SW8: number of floppies.
If correct your is set to normal, no mathco, 256k or more ram, Mono adapter, 2 floppy drives.

I can get a picture of the whole board, I dunno how much help it will be as far as identification given that those BIOS ROMs are the only branding I've found so far though.
People can identify things from the entire board layout or visual looks common to a certain manufacturer. In fact, the BIOS branding can be completely obscure, done by whatever firm bought the thing from Taiwan, and made it their own, but it's really some generic Taiwan board that you can derive the switch settings because it's basically identical to other brands.
I took a few more pictures, sorry it took a few days. Dunno if any of these help at all.
THanks ! It appears to be same board as in this topic: Re: Retrofanatic's "8Mhz TURBO BOARD" NEC V20 XT Build

Thanks Horun! This info will help a lot when I get a CGA/EGA card for this system.

Nice socket expansion roms!. You can expand motherboard functions, like add a 2m+xbios (adds compatibility with high density floppy drives), IBM basic, xt-ide...etc.
Well, then You need a cga/ega monitor 😀.
Meanwhile You can test the motherboard with some Realtek/hmc/Cirrus/trident 16bit vga. Some of this cards, works in 8 bit ISA bus.
