Very odd. It worked perfectly for a day. Just long enough to install the
OS and get happy. I came down in the morning and hit my usual "shift"
key to wake it up, and nothing. OK, so I power cycled it. fsck... Back
up. Great.

Next morning, same routine, and irritation. Geeze, I just got the thing,
now this!? Power cycle...

Dead again when I came home. And again later (I get home early).

Next day, it happened while I was sitting there. That's when I saw the
panic messages about cpu ecache sram data parity errors, and
check_misc_error. 

Then it was more frequent. Like half an hour. That's when it was
suggested that I clean the DIMMs. I did, and started to get all sorts of
errors;

Memory Address not Aligned
Fast Data Access MMU Miss
Instruction Access Error

You know, fun stuff. :(

I gave up. Considered getting some DIMMs to stick in, but they ain't
cheap, and I'm on a budget. I decided to throw in the towel and get a
U30 or 60 from Comdisco (still might, those 30's *are* cheap). So I
pulled the SCSI drives to stick back in the Linux box, and put the IDEs
back in.

What the hell, I booted it just to see what would happen. And it
happened. We'll see how long it lasts. 8 hours now.

I loaded the SunPCi software, but don't have a copy of windows. Will it
run any other OS?

Also, assuming this box stays up and is actually usefull, can I mount
the drives with "logging" on IDE? I assume it's based on the filesystem,
yes? So media doesn't matter.

Can I swap these drives for faster ones? They're Ultra ATA33, and now
there's Ultra ATA<something faster>. Anyone know? Or is the bus speed
the limit? I don't know these things, the only IDE I have is in my
laptop and a Javelin Wedge.

Thanks,
