Pretty nice system. :)

sounds exactly like the problems I was having. I solved it in the end by
plugging a floppy sized power connector for the motherboard, backfeeding what
usually power the floppy drive in a desktop A1200.
I also had to backfeed the PPC via the fan power connector. The adaptor for this
was bought from Eyetech.
In addition to this, I rigged a PSU fan to blow air onto the ppc card - I am not
convinced that the small fan on the BlizzPPCs is enough... I've got a Power
Tower here, so if I say I superglued the fan to the front right edge of the PSU,
you should understand what I mean. I hope. :)
I also had to put a heatsink and fan on my bvision, and upgrade to CGX4 to
finally cure all my problems.

Power Flyer... *shudder* lost two harddrives and a set of 3.0 ROMs to one of
them.
When I was investigating my problems, the guy (Ian?) from White Knight informed
me that the BlizzPPC needs at least 8 meg of ram to boot. And I think I remember
reading that in the BlizzPPC (ahem) manual.

try taking the big black heatsink off the ppc, remove the dust from there, mine
attracts a LOT of dust there. Check to see if you need more heat transfer
compound on the PPC, my card was supplied with such a small amount it wasn't
even making contact between the chip and the heatsink.
It's an 040 PPC too, so a heat sink and fan there might help, it did here.
Also, a washer between the chip in the very corner, forget which, but it is a
very small chip which almost makes contact with the heatsink helps.
In all, I had a lot of problem with my 040/25 630e+/240 when I added a
blizzardvision, but after a few months of trying things, its all been worth it
and the machine is very nice to use now. :) The only regret I have is not
waiting "six to eight weeks" for an 060 version of my card, and yes, it's a big
regret.
Carpe Diem,
Mike O'Hara
