NCR SCSI BIOS and Drivers
The NCR 53C810 SCSI BIOS resides on the same flash memory chip as the
system BIOS. To use the onboard NCR BIOS, you need to install an NCR
53C810 SCSI controller card in your system.
All SCSI devices that you install in your system require software drivers. The
NCR SCSI BIOS directly supports SCSI hard disks under DOS, Windows and
OS/2. It also uses DOS-format and SCO UNIX-format support floppy disk
device drivers that come with the NCR 53C810 SCSI controller card. The
DOS-format device drivers are for SCSI devices used with DOS, Windows NT,
Novell NetWare and OS/2. The SCO UNIX-format device drivers are for SCSI
devices used with SCO UNIX. These drivers offer higher performance than
the direct BIOS support.
To use the device drivers, you must install them in your system hard disk drive
and add them to your system configuration files. For detailed installation
instructions, see the README files that come with the drivers.
