Hi Vogons
I've been tried to get a new motherboard purchase up and running.
After much testing and troubleshooting I have determined the cache is faulty.
I have some chips I have pulled from a dead 386 motherboard, and was hoping to use these. However I am unable to find any information on them online (I am hoping they are compatible with my board). Can anyone shed some light?
I've attached some photos.
Installation history as follows...
FYI the board arrived with the CPU voltage regulator snapped clean off.. thankfully I had planned to use a 5volt 486DX2 66. The board is booting with this fine.
1. Tried various ram combinations. Seems the system will only POST if the 4 simm slots are all populated. Ram at boot totals 3712KB
2. Found working HDD, Installed dos 6.22 OK. Rebooted a few times with no issues.
3. Did some cable management...
4. System boots and starts giving a XMS error (see pic attached)
5. Tried replacing all ram chips. No change
6. Disabled external cache and error goes away
7. Enabled cache (error returns) and tried a few dos operations - system unstable
8. Disabled cache and system is stable
Is is strange the cache initially seemed to be fine. Then the XMS error started after I was (carefully) tinkering in the case adjusting the layout.

Take that there and put it in here
