Intellisafe - Smart; Automatic Soft-Drive Types - Compaq DESKPRO 2000 SERIES Maintenance & Service Manual

IntelliSafe - SMART

The IntelliSafe IDE hard drives for the Compaq Deskpro 2000 Series of Personal
Computers have built-in drive failure prediction that warns the user or the network
administrator of an impending failure or crash of the hard drive.

Automatic Soft-Drive Types

An automatic soft-drive type is a 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 automatically builds a soft-drive type when it finds
that a hard drive is not in the hard drive parameter table.
The soft-drive types assign according to the table below:
Drive
0
1
0
1
For hard drives that are greater than 528 MB, the system automatically translates the
hard drive parameter for DOS by logically halving the cylinders and doubling the
heads. This allows DOS to access greater than 528 MB. The translated hard drive
parameters are put into the hard drive parameter table in the shadow RAM copy of the
system ROM. When using any operating system other than DOS, you must use the
Compaq User Diagnostic diskette to set up the hard drive parameter table without
translation.
