Adaptec 7800 Family Manager
My computer does not recognize my host adapter.
During bootup, check to see if the BIOS message for your primary
7800 Family host adapter appears. If the messages do not appear, the
host adapter may not be properly configured; check the following:
■
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.
