Adding hardrive

[Gregory J. Neumann]

What kind of bus?  IDE or SCSI?  Do you have the jumpers set 
properly (Master/Slave/CS)?  Is the drive listed in the BIOS setup?  
The latest and greatest BIOS's with the "onboard IDE" controllers 
usually have the ability to enable/disable them in BIOS, and if the 
controller is turned off, RedHat will never find it.  Does your BIOS 
have an "auto-detect" feature?  If so, did it find the drive?
Whew! Ask a simple question and get 99 as a "helpful" reply! ;-)  
Hope some of this helps.
