Fireball 540AT
| 3.5-INCH DISK DRIVE AT
CONFIGURATION |
For IBM PC-AT® and compatibles, a
master/slave relationship must be
established for the hard disk drives on the ATA bus. If only one
hard
drive is installed on the ATA bus, it must be configured as the
master
drive.
If two hard drives are installed on the ATA bus, one must be
configured as the master and the other as a slave.
The drive position on the cable (first or last physical device
on the
cable, for example) has no effect on the master/slave
relationship.
The jumper settings solely determine the master/slave
relationship. |

* The drive can be configured as master or slave either
with the CS

to find out if your system supports the cable select feature). To
configure the drive as a master or slave with the CS feature, the CS
jumper is installed. |
