The helpdesk technician has been tasked to reinstall the OS on a desktop and has already
inserted the OS install disk in the CD-ROM. Which of the following would MOST likely need
to be configured within the BIOS to continue reinstalling the OS?
A.
BIOS password
B.
Flash BIOS for firmware upgrade
C.
Boot sequence
D.
Clock speeds
Explanation:
To boot the OS from the CD ROM, you need to change the boot sequence to boot from CD
ROM first. Normally, the boot sequence is to boot from hard disk and if it is unable to find
boot files there, it will look for it in a CD ROM. After that, it will look into other places like a
floppy disk drive and PXE boot.
In computing, the Preboot eXecution Environment (PXE, sometimes pronounced as pixie) specification describes a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients
