Well, I don't have the manuals with me to give any specifics about my
machine, but I think the 3-chip parity problem is caused by the BIOS
incompatibility.
This is what happened to me.
I had 4Meg of 9-chip simms and bought 4 more 3-chip simms. I installed it
with ease and boot up. The computer would tick for 4Megs then hangup.
CMOS chipset error! So, I turned off the above 1 meg memory check off and
no problem. I then proceded to windows and decided to use all 8megs of
memory. So I open up a BIG TGA file. Parity error in the middle of loading.
So I put the 3-chip simms on the first bank (making them the first 4 megs).
Now, CMOS error occurs as soon as it starts memory test. So I turn parity
check off in my BIOS setup. Now, it runs with no problem. Windows gave me
no trouble. Of course, when I installed OS/2 2.0, I stated getting that
parity error again.
But, my point is that since I was able to fix the problem, at least temporarily,
I believe that it's the BIOS that causes 3-chip simm incompatibility.
AMI Feb/91 (I think).
