External HDD Boot Support
Enabled
Disabled
Enables/Disables the boot option ROM for the second onboard
hard disk controller, which drives the second parallel ATA channel
and the two SATA channels.
Note: When set to 'Enabled', the system must be rebooted in
order for the SATA device to be visible in the boot option ROM
initialization.
Network Boot Support
Enabled
Disabled
Disable/Enable PXE network boot support to LAN.
Note: When set to 'Enabled', the system must be rebooted in
order for the Intel Boot Agent device to be visible in the Boot
Device Priority Menu.
Notes
Due to the lack of upper memory area space for option ROM initialization, it is not
possible to enable external HDD boot support and network boot support at the same
time. Only the first detected option ROM will be recognized.
The first and the second SATA channels are handled by the VIA VT6421 Serial ATA
controller located on the conga-XLX. The driver for this controller can be found on the
congatec website. There are also special instructions included as a README file within
the driver package that explains how to use a hard drive that is attached to this
controller as an OS installation drive for Windows XP and 2000.
