Adaptec 7800 Family Manager
■ The 7800 Family host adapter supports level-triggered interrupts and
can share the same interrupt with another 7800 Family host adapter or
PCI hardware that also supports level-triggered interrupts. Check
your host adapter’s User’s Guide and your computer documentation
for details in configuring IRQs and other parameters in the system
CMOS setup.
■ The Boot host adapters should be installed into the lowest PCI
Device number. The Device number is determined by the slot
number on the PCI bus.
To find out the Device number of your 7800 Family host adapter(s),
run the SCSISelect utility (by pressing a key combination displayed
onscreen at bootup). Look on the first screen of SCSISelect in the
upper right hand corner for Bus:Device xx:xxh (given in hex).
If the Device number is high, power
OFF
the computer, move the
7800 Family host adapter to a PCI slot at the other end of the
motherboard, and rerun SCSISelect to see if the number is lower.
The host adapter LED lights during activity. This light helps to
determine which adapter SCSISelect displays information for. Refer
to your system documentation for further details on determining the
PCI slot number and slot number order in the system.
