These likely are hold-overs from ancient days where the default was
15s... I'd be surprised if aha still even worked, but I have no way
to test it easily these days: I have the cards but no active systems
with ISA slots. ahb never was my baby, but my only EISA system has
been off for at least 4 years now, and likely won't be turned back on
ever...
But regardless, neither of these controllers references SCSI_DELAY.
Cam likely can remove it safely as well, but I'd be more leery of
doing it there since I'm chicken :)
