BIOS Write Protect Jumper: JBIOS1
A "boot block" program is included as part of the system BIOS to recover the system
from a situation when the BIOS code is incorrect/corrupted or needs to be updated.
W hen the BIOS code is corrupted or needs to be updated, you have to at first disable
the write protect function by shorting 1-2 pin of the JBIOS1 jumper. Then the boot
block will try to recover the BIOS code, usually by reading it from a specially-pre-
pared floppy disk.
Under normal operation, we suggest that you enable the write protect function by
shorting 2-3 pin of the JBIOS1 jumper to protect the boot block from virus infection.
