Cable-Select Technology
The Compaq ProLinea Family of Personal Computers uses cable-select
technology for identifying Device 0 (master) and Device 1 (slave) IDE hard
drives. Check that the jumpers on the IDE hard drive are set properly for
cable-select installation.
Soft Drive Type
The Compaq ProLinea Family of Personal Computers supports an automatic
soft-drive type mechanism where the system ROM and Computer Setup provide
support for IDE hard drives that are not supported in the hard drive
parameter table. Computer setup will automatically build a soft-drive
type when it finds that a hard drive is not in the hard drive parameter
table. You can also change or add a soft-drive type with Computer Setup.
The hard drive parameter information is stored in NV-RAM. The system ROM's
POST copies the hard drive parameters into the hard drive parameter table
in the shadow RAM copy of the system ROM. After POST, the soft-drive type
appears as a hard drive type.
The soft-drive types are assigned to hard drive types as shown in
Table 6-15.
