: That means that is bus 01, device 09, and function 0. Correct? That means that
: dev(ctrl(pci[pci_num]),slot[,func_num[,ctrl_id]])[,dev_id[,LUN]])    ==
: sd(apsc(pci(0),3,0,7),9,0) ?

bus is going to be 1 here.  slot == device since it makes little sense
to mix scsi and pci IDs in that part of the string to me and
bus:dev:func is fairly standard notation (with variation in
punctionation) and dev_id would be 1, since that's the SCSI ID (where
it does make sense to use scsi IDs).

: I think that ctrl_id is my Adaptec adapter (7, according to Adaptec
: mgmt) and dev_id is my SCSI HDD = 1 according to jumper setting and
: Adaptet mgmt).

I don't think that ctrl_id is 7.  Your SCSI ID for the controller on
the scsi bus is 7, but the SCSI ID for all controllers is 7.  If you
had a dual channel scsi card, you'd have to distinguish channel A from
channel B, and that's usually going to be encoded 0/1 or 1/2 (more
typically the former, but I don't know DGUX specifically).

So wouldn't that be sd(apsc(pci1),9,0,0),1,0) or more simply
sd(apsc(pci1),9),1)?  Hmmm, the above expression has too few ) so I'm
thinking based on the original boot command, it should be either
sd(apsc(pci(1),9,0,0),1,0) or more simply sd(apsc(pci(1),9),1)

Maybe this will be helpful.  But that's just a shot in the dark.
There also appears to be a PCI bridge in the new system that isn't in
the old system, since the card is on pci bus 1 and the boot loader is
looking for it on pci bus 0.  This likely isn't a huge deal since the
BIOS of that vintage PC will initialize the bridge correctly.
