My A1200(rev 1D4)/Bppc/Bvision wouldn't even boot without a second power line to the floppy. i won't run a power line to the fan port as this didn't really work for me.
however. i did have the latest firmware (G-REX) on my blizzard card when i got my Bvision, and it wasn't a happy bunny at all. when i reflashed my BPPC back to the latest firmware for the Bvision only, it was fine.
the other thing i have trouble with, is occasionally, i need to "wiggle" the bvision on its connector with the BPPC. as the machine boots up fine, but it won't display a CGX screen. a hint that its having problems, is the bvision mode promoted aga screen is slightly corrupt, and the mouse pointer is a load of dots. a quick couple of presses on the connector and everythings fine.
my A1200 rev1D4, BPPC, and Bvision are solid as rocks. i've not had a lockup, guru, crash, or reboot. :-? i was looking at doing the timing fixes, but i havn't had any problems, so no real reason to...
but the bvision does suck alot of juice. i have an 80Watt nano ATX PSU, plugged into a d-box Amiga ATX to AT adapter.
The mainboard powerfeeds comming from the D-box adapter feed the PSU port, plus a 5V mainboard line goes to the 5V of the floppy port. the drive leads from the nanoATX psu run the floppy, DVD, fan for Bvision, fan for BPPC and the 12V and ground lines of the floppy port.
i wouldn't like to run a BPPC/BVision A1200 on an A500 PSU. i can't say for sure, but i think power may be the problem, plus check which firmware you have on your BPPC.
