Managed PC Boot Agent
This CardBus PC Card ships with
3Com’s Managed PC Boot Agent
v.4.01 for Pre-boot Execution
Environment functionality (PXE 2.0).
PXE support enables computers to
boot from a network server, allowing
automated setup/configuration of
new and existing computers,
decentralized software distribution,
and remote troubleshooting/repair of
damaged computers.
To use the Managed PC Boot Agent,
your notebook must have a PXE 2.0
compliant BIOS.
Please consult your notebook
vendor to confirm whether your
notebook’s BIOS supports PXE 2.0
for CardBus. For NetWare and
NDIS, make these changes:
• For NetWare, add the keyword
PXEBIOS to the NET.CFG
configuration file in the 3Com
driver parameters section.
• For the NDIS 2 driver in a
DOS environment, add the
keyword PXEBIOS=1 to the
PROTOCOL.INI configuration file
in the 3Com driver parameters
section.
