To make this change permanent, you can add the product identification string to a table in the Srom driver's space.c file. To do so:
When the device is opened, the strings are displayed. You must relink and reboot your system after editing this file.
The system will now automatically recognize your CD-ROM as a device requiring ten-byte SCSI read commands.
Contact your hardware vendor about your device's read command requirements; see also the Srom(HW) manual page.
Identifying the installation media device Media device to be used: IDE CD ROM
IDE Controller: primary Master or Slave: slave
If you have this problem, the boot hardware information display will be similar to:
%adapter 0x0170-0x0177 15 - type=IDE ctlr=primary dvr=wd %tape - - - type=IDE ctlr=pri cfg=slv dvr=Stp->wd %cd-rom - - - type=IDE ctlr=pri cfg=slv dvr=Srom->wd
This problem has been encountered in some Toshiba notebooks. To correct it, rerun the initial configuration routine and set the controller values to:
IDE Controller: secondary Master or Slave: master
If you encounter problems, add wd.noscan to your bootstring to prevent scanning during installation. If you need to configure additional hard drives, do so after installation is complete. This bootstring is not required after installation. See bootstring(HW) for more information.
Systems that include single types of mass storage devices (that is, EIDE/ATAPI or SCSI only) do not need this bootstring.
