hi, i'm new to this mailing list. i was just setting up a college linux
server and the `scsi' boot kernel couldn't recognize the bus logic
controller. i was using a 2 year old, slakware 3.0 (kernel 1.2.13)
distrib.
i'll try to use a newer distrib tomorrow. the port address for the
controller is 0x6000 and the base address is 0x8000. could that be the
reason for the problem ?
I assume this is a BT-948/958/958D, in which case your problem is that the
obsolete BusLogic driver in 1.2.13 does not have PCI support. See below for
how to fix this. If it turns out you are trying to use a FlashPoint host
adapter, you'll need to move to a more recent Slackware and the boot kernel is
available from http://www.dandelion.com/Linux/ (as is further BusLogic on Linux
information).

BT-948/958/958D INSTALLATION NOTES
The BT-948/958/958D PCI Ultra SCSI Host Adapters have some features which may
require attention in some circumstances when installing Linux.
o PCI I/O Port Assignments
When configured to factory default settings, the BT-948/958/958D will only
recognize the PCI I/O port assignments made by the motherboard's PCI BIOS.
The BT-948/958/958D will not respond to any of the ISA compatible I/O ports
that previous BusLogic SCSI Host Adapters respond to. This driver supports
the PCI I/O port assignments, so this is the preferred configuration.
However, if the obsolete BusLogic driver must be used for any reason, such as
a Linux distribution that does not yet use this driver in its boot kernel,
BusLogic has provided an AutoSCSI configuration option to enable a legacy ISA
compatible I/O port.
To enable this backward compatibility option, invoke the AutoSCSI utility via
Ctrl-B at system startup and select "Adapter Configuration", "View/Modify
Configuration", and then change the "ISA Compatible Port" setting from
"Disable" to "Primary" or "Alternate". Once this driver has been installed,
the "ISA Compatible Port" option should be set back to "Disable" to avoid
possible future I/O port conflicts. The older BT-946C/956C/956CD also have
this configuration option, but the factory default setting is "Primary".
