referred to as DOS Compatibility Hole (DCH) space. This space is limited. This F10 option will allow
users to disable the downloading of this embedded NIC option ROM thus giving more DCH space for
additional PCI cards which may need option ROM space. The default is-enabled.

This method of recovery requires that you rst perform the Save to Removable Media command with the
Computer Setup (F10) Utility before Restore is needed. (See Computer Setup—File on page 41 in the

NOTE: It is recommended that you save any modied computer conguration settings to a USB ash media
device and save the device for possible future use.
To restore the conguration, insert the USB ash media device with the saved conguration and perform the
Restore from Removable Media command with the Computer Setup (F10) Utility. (See Computer Setup—File
