BBS BIOS-Compatible PCs

To enable a BBS BIOS-compatible PC to boot from the network using the MBA boot ROM:

1Make sure that the NIC boot ROM setting is Enabled.

See the previous section, Enabling or Disabling the Boot ROM Setting, for instructions.

2Set the MBA manually as the first boot device in the

PC BIOS.

Refer to your PC documentation for instructions on accessing and configuring the PC BIOS.

3Reboot the PC.

The MBA attempts to boot from the network using the default boot method PXE.

CAUTION: For computers running Windows 98, boot directly to DOS instead of restarting in MS-DOS mode from Windows 98. The MBACFG.EXE program will not work properly if you restart in MS-DOS mode with the 3CR990 NIC drivers loaded.

To change the default method or any other MBA configurations, press Ctrl+Alt+B when the following message appears:

Initializing MBA. Press Ctrl+Alt+B to configure...

If the network boot fails, the following message appears:

Network boot aborted, press any key to continue

The BIOS continues to the next device in the boot order (for example, the local hard drive).

To cancel the network boot, press Esc anytime during the network boot process.
