The Symbios (NCR) 810 PCI SCSI-adapter does not have an on-board bios.
To properly use an NCR 810, your motherboard must offer bios support.
Have you verified that your Aptiva has proper bios support? Even though
OS/2 doesn't use the bios for disk i/o once the driver is loaded, the
bios is necessary for proper initialization at boot time. It may be
that the controller is not being initialized correctly.

Users of motherboards without explicit bios support for Symbios/NCR SCSI
chips should use the Symbios (NCR) 815 instead. The NCR 815 has its own
onboard bios. Under OS/2 the bios is primarily used for initialization
during booting.

I'm unaware of any way to reload the drivers without rebooting. One
interesting programming project would be to write a freeware driver for
the NCR based on the Linux source code. IBM has made the OS/2 DDK free
via its web site. Such a driver could be made to accept commands via
user mode utilities.
