Basic hardware configuration

ATAPI/EIDE peripheral bootstrings

The bootstring to specify the location of an ATAPI device (such as a CD-ROM, tape, or LS-120 drive) on the EIDE (IDE) bus is:

periph=wd(number, 0, ID, 0)

The parameters in this bootstring are:

periph

Internal name of the peripheral interface driver. Possible values are:

Sflp: floppy disk drive (including LS-120/240 drives)
Srom: CD-ROM drive
Stp: tape drive

number

The ATAPI/EIDE device, where 0 specifies that the device is attached to the primary controller and 1 specifies it is attached to the secondary controller.

ID

The controller ID, where 0 indicates that the device is master and 1 indicates it is slave.

For example, to specify a CD-ROM that is on the secondary IDE controller that is set to master, enter:

Srom=wd(1,0,0,0)

If the CD-ROM is the only device on the IDE interface, it must be set to master.

NOTE: Please note that you cannot specify IDE hard drives in the same manner. If IDE hard drives are present, the installation uses the Primary/Master IDE hard drive as the root drive.
