I recently purchased an A7N266-VM and have experienced similar problems on bootup with grub and lilo. Here is a quick overview my experience. Hope this is useful.
A7N266-VM
Athlon XP 2000+
DDR266 256MB (x1)
WD 7200 80Gig ATA100
Samsung CDRW & DVD drive (ATA 66/33 respectively)
Linksys 10/100 NIC (for network installations)
Problem:
- Error 28 on boot under grub ("Error 28: Selected item cannot fit into memory")
- Under Lilo I get the letter "L" and a locked system.
- Floppy rescue boots normally.
- System locks up when starting X after floppy boot but this is probably due to using the default 'nv' driver and wasn't a concern.
Attempts:
-Reinstalled with various configurations:
--- / partition 20Gig and 2Gig (to see if it was a hard drive capacity issue) -- NO CHANGE
--- from CD instead of network -- NC
-Transfered another working drive to this box -- NC
-Swapped memory locations -- NC
-Disabled all non critical chipset features in bios -- NC
For my sanity, I installed 98SE with full updates, drivers and patches (for OS and chipset) just to see if it would work. The box turns out to be an acceptable windoze platform: Q3A played fine, UT played fine but couldn't get the sound right (sounded good but seriously choppy). CD's played beautifully.
Conclusion:
The board works fine under 98SE and appears to work fine under RH 7.3 & 8.0 if you have a means to bypass grub and lilo. (CD, floppy...) Otherwise it will never boot and is almost as useless and troublesome as a WinModem...
I will be returning the board next week but for what I'm not sure yet. Anyone have a solid recomendation as a replacement. I will need to accomodate the rest of the components (memory, CPU, etc).
Thanks in advance,
