Often called a "no name" this small 386 board has lots of jumpers and some solder bridges I'm trying to figure out what they do. Can't seem to find any exact matches anywhere. There was someone on youtube that showed they had the manual, but not the contents. If there is anything online I'm missing or you have this manual and can scan it, that would be greatly appreciated.
Thanks,

There are 3 very similar looking boards on UltimateRetro:
https://www.ultimateretro.net/en/motherboards/6803
https://www.ultimateretro.net/en/motherboards/2497
https://www.ultimateretro.net/en/motherboards/6813
of which the second one (Gemlight) has a MicroHouse sheet with some settings that might help: https://www.ultimateretro.net/motherboard/manual/32104.pdf
I have the same board if it looks like top Picture in 6803 link (that is my board, and BIOS string has ECS ID#).
The jumper at J5 is open to use the Power Good from PSU and J6 is hardwired because it uses the ALI M5818 RTC/CMOS chip and not a different one AFAIK.
The jumper J7 is hardwired Closed (on my board) to always check for Parity. You can read the Silk screen on 2497 or 6813 which tells you nearly everything except J9.
J10 is Sync/Async for the Mathco. If Sync you need a 40Mhz one, if you use a 33Mhz then you need a crystaI in OSC1 and jumper it to Async mode.
....never figured out what J9 does. Edit fixed my error. Am working on a board layout and jumper sheet based on the Silk Screens....
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
Here not sure if this helps, may have errors as I quickly threw it together as I was cooking dinner

Thank you all. Any idea what the bridgeable CP2 or CP3 pads set?
