Re: Installation Woes - Update - AMD 64 MB Recommendation??

I removed all drives from the system but the number one IDE hard disk
and the IDE DVD/CD drive. The IDE 32 Gb drive was partitioned for 2
gb for the operating system and 30 gb for whatever, with the 2 gb
partition made primary. There is no SCSI stuff in this test system
(other than the controller itself which I was too lazy to take out).

I installed a new os/2 system on this partition (processor operating
at 1100 mhz). I got beyond the refusal of OS2CDROM.DMD refusing to
load by putting IBMDECD.FLT back into CONFIG.SYS.

The installation went normally and seemed solid. However, I could not
boot with the processor set to 2200 mHz. The machine would hang at
the os/2 blob or just before it. I did get it to boot at speeds up to
1833 mHz but not at 2200 mHz.

Thus I come to the conclusion that the motherboard has developed a
problem that manifests itself at higher operating speed.

I did this test with my old (3200) processor, but since I had problems
with higher speed with the 2800 processor, I think the MB is much more
likely the problem.

The only anomaly that occurred is that I got DOSCALL1.DLL error
causing boot to fail (at any speed) when I added my SCSI driver
(TMSCSIW.ADD) to CONFIG.SYS. I wanted to try to access the SCSI
drives when booting from the IDE. I'll leave that problem for another
day.

I will still improve my SCSI cabling and controller to get full
transfer speed, but that does not seem to be the underlying problem.

I will get ECS 1.2 before changing the motherboard. In the meantime,
I'll keep operating at lower speed.

Thanks to everyone's help.
