I have a Packard-Bell 486 machine on which I am installing a second hard drive. The machine has the Phoenix BIOS v1.01, and uses DOS 5.0 and Windows 3.1. The "C" drive is an IBM hard drive with a capacity of 1215 MB. The Ontrack v7.09 Disk Manager software is installed on it to allow the use of a hard drive greater than ~528 MB. At present the jumpers on that drive are set to "cable select". The hard drive I am trying to fit to this machine as "D" is a Western Digital Caviar 14300. The Wester Digital Part Number is AC14300-00RTT1. The new drive has jumper settings for SLAVE, NASTER and SINGLE, but so far as I can tell, none for "cable select." At present, the BIOS does not recognize the existence of the new drive. My questions: 1) How do I set this new drive for "cable select"? 2) Will wrong BIOS settings caues the drive's existence to not be recognized? Thanks, Kurt
