> I installed an ATTO UL2D SCSI card in my beige 266 rev 1.
Peter's reply and my further intermingled confoundedness follows thusly:
UL2D cards are a strange beast.
They have two indepdent SCSI processing cores plus a PCI bridge.
These should appear as:
Multifunc-device, vendor ID -1, and card model -1
ASP cannot see past the card's PCI bridge to see what the card really is.
Which is only part of the problem with these cards.
Although there are places for two external VHDCI connectors, only the one for Bus 0 is stuffed (on most examples), and of the two internal connectors, only the one for Bus 1 is sufffed (again, on most examples).
This card only has one external connection (mini 68 pin) channel 1, and one internal regular 68 pin connector, channel two. I guess this is Apple's OEM version?
To reliably boot from this card, you must stuff the empty internal connector, in order to have an internal Bus 0 device.
Once again, only one connector here.
Optionally, you can use an external device, as that is also Bus 0.
Booting from the card's Bus 1 is problematical at best.
The earlier ExpressPCI DC would show up as two SCSI cards, both being in the same slot, and it didn't have these issues. Also, both VDHCI connectors and both internal conectors were stuffed (on most examples).
Trying to stuff the empty VHDCI connector slot (which is Bus 1) is difficult, tedious work, and may lead to a nonfunctional board.
This makes me think you are talking about soldering another connector onto the board or something crazy??? !!! "Stuff" ?
This card auto-terminates the host adapter, and only in extreme cases is it absoluely necessary to terminate the last device.
I only plan on using one device, so it should be the last device, but it's the Seagate Cheetah model ST118202LC and it requires termination. Doesn't terminating the end of the SCSI chain apply here? The manual states I need active negation and also says the following:
"If the drive is the only device on the bus, attach it to the end of the SCSI bus cable. The user, system integrator,or host equipment manufacturer must provide external terminators".
"ST118202LC drives
These drives cannot furnish terminator power because no conductors in the 80-pin I/O connector are devoted to terminator power."
"ST118202LC drives are designed to be
plugged into a backpanel connector without cabling."
The main advantage of this card is it is 64-bits and LVD/SE.
A seecondary advantage of this card is it is two completely independent SCSI cards, sharing one PCI slot (and, therefore, needing only one PCI slot).
OK, this appears helpful but please clarify what you mean by the term "stuffed" and tell me what you think about the fact that I updated the card ROM to 1.64 from the OEM Apple ver. 1.43 (while I was booted in 9.2) and now after reboot the system hangs immediately at the happy mac when trying to start up in 9.2 while booting from my original ATA drive.
