Here is my issue: I have a Aopen/Acer branded motherboard, socket 3, model VI15G with DX2 66Mhz. The board was working great until I decided to change out my case. I stripped everything out except the CPU and cache. Once reassembled in the new case, I installed all cards and a IDE/CF adapter. I was able to install DOS 6.22 without issues (except having to run fdisk /mbr after install). Upon Himem.sys initialization, I get a error saying "himem.sys has detected unreliable xms memory at xxxxxxxxx. So, I tried switching out the system memory; same issue. I've tried to run Memtest86 and it crashes upon "cachespeed' something or other. I was thinking maybe the cache jumpers were set wrong, so I set them to 1) what was printed on the mobo 2) jumper settings per the internet. Ive also tried to disable external cache in the bios; doing so everything works fine which is leading me to believe I have 1) bad cache 2) bad mobo. Any suggestions or something I'm over looking? I can't change the cache out as I dont have any 32pin dips.
I'm really hoping the board isn't dead as its a nice mobo!
