Well . . . :-/ . . . I spent the day recasing a really fugly 6500 into my DigitalSTATION_910 box today and I think I blew up my $18.00 Two Slot Adapter (for another hack) testing the possibility of hoodwinking the MoBo into allowing the use of Three Standard PCI Slots if there was a Modem in the COMM Slot.

It was just a hunch, the only time I got results for one of the slots on the cabled riser was when I had two identical Video Cards installed, one in the bottom slot of the 6400 Riser and one in the first, straight passthru, slot on the cabled riser. Interestingly enough, the Card in the riser worked fine . . .

. . . but it disabled the card on the bottom slot of the stock riser. :?:

I tried another Video Card in the riser, but I knocked it over and something that apparently should NOT have been grounded, hit the PSU case and pole-axed the system instantaneously. After that, the 6400 wouldn't boot anytime the Two Slot Cabled Riser's plug end . . .

. . . was plugged in. :disapprove:

The ID SEL for the Second Slot has jumpers for AD 31-20 which is tied in with a 28 pin SMT IC with the legend:

IT8209R

0950 - AYT

ZFAM74 L

The PCB says:

Comply with

ROHS

Standard

It's all Greek to me, but maybe it makes sense to one of our EEs, just maybe? :?:
