Jumper Settings B-3
BIOS Recovery Jumpers
If an interruption occurs during a BIOS upgrade that prevents continuation of the process,
it is possible that the BIOS may be left in an unstable state. If this happens, BIOS Recovery
must be performed. This entire procedure is performed in conjunction with a BIOS
Recovery diskette. This procedure is seldom required; if it is, see the instructions that are
provided with the diskette.
You can obtain the BIOS Recovery program by downloading it to a diskette from the
NECCSD Bulletin Board System (BBS) or the NECCSD File Transfer Protocol (ftp) site.
See “NECCSD Bulletin Board System” for information on accessing the BBS. See
“Internet” in Section 4 for information on accessing the NECCSD ftp site.
In order to perform BIOS Recovery, pins 1, 2, and 3 on J1A1 must be unjumpered.
HARD DISK DRIVE JUMPER SETTINGS
Hard disk drive jumpering varies according to the particular model in the system and how
that model is configured. The following subsections provide jumper settings for Seagate
Medalist, Quantum Stratus, Seagate Barracuda, and Quantum Viking hard disk drives.
Seagate Medalist

Slave
None
Master (in single or dual-drive system)
5-6
Master (with non-ATA-compatible slave)

3-4.
Quantum Fireball Stratus
The Quantum Fireball ST (Stratus) Ultra DMA drives use a three-position jumper block to
configure the master/slave and cable select options of the hard drive. The user selectable
jumper is shown in the following figure and its settings follow.
