Installing SCO OpenServer 5.0 on
XEN-PC/PCLS/PCM with ATAPI CD-ROM
Releases of SCO Unix prior to OpenServer 5.0 have only supported SCSI
CD-ROM drives. However, ATAPI CD-ROMs that connect to an IDE interface are now supported
by OpenServer 5.0.
The driver for the ATAPI CD-ROM is supplied as a BTLD floppy and is
included in the SCO packaging.
The CD-ROM for the XEN-PC/PCLS/PCM, apart from the A1 DX/2-50, is now an
ATAPI type. At the current time such models are RC, RD, RE, RF, RG, and RH product codes.
Installation from an ATAPI CD-ROM is discussed in the OpenServer 5.0
Release Notes booklet, but the boot string given below will be required to install the
product. To install, carry out the following:
- Ensure that the CD-ROM is connected to the secondary IDE interface and is
strapped as master.
- Boot the machine from the SCO OpenServer Boot Disk.
- At the Boot: prompt enter the following:
defbootstr ahslink=ATAPI Sdsk=wd(0,0,0,0)
- When requested whether or not to replace the wd driver, select r to
replace.
- A screen to identify the installation media will be displayed. Select
SCSI CD-ROM.
- Select wd as the SCSI host adapter type.
- Select 1 as the host adapter number.
- Select 0 as the SCSI ID.
The ATAPI BTLD replaces the wd driver normally used for IDE hard disks
with a new version that supports ATAPI CD-ROMs. With this driver, hard disks and ATAPI
CD-ROMs appear as SCSI devices.
Once OpenServer 5.0 is installed the SCO OpenServer Release Supplement
should be installed. This is the same floppy as above - it includes the ATAPI BTLD. Refer
to chapter 4 of the OpenServer Handbook for instructions on applying a software patch with
the Software Manager.
