Booting with the
MBA Boot ROM
The boot process for the MBA boot ROM varies depending on the type of PC
you have (BBS BIOS-compatible or non-BBS BIOS-compatible).
If your PC was purchased recently, it may be BBS (BIOS Boot Specification)
BIOS-compatible. The BBS determines how the system BIOS identifies boot devices
in a PC (such as a CD-ROM drive, a hard drive, or a floppy drive), allows the user
to select the boot order of these devices, and then attempts to boot from each
device sequentially.
Refer to your PC documentation if you do not know which type of PC you have.
BBS BIOS-Compatible PCs To enable a BBS BIOS-compatible PC to boot from the network using the MBA
boot ROM:
1 Make sure that the boot ROM setting for the NIC is Enabled .
For instructions
Go to: Enabling or Disabling the Boot ROM Setting .
2 Manually set the MBA as the first boot device in the BIOS for your PC.
Refer to your PC documentation for instructions on accessing and configuring
the BIOS.
NOTE: For detailed information on using, configuring, and troubleshooting the
MBA boot ROM, see the documentation for MBA on the EtherCD that shipped
with this product.
