This a llows you to configure your system to the type of IDE disk controller in
use. By defa ult, Setup a ssumes tha t your controller is a n ISA (Industry Sta nda rd

is the type of slot being used.
If you ha ve equipped your system with a PCI controller, cha nging this a llows you
to specify which slot ha s the controller a nd which PCI interrupt (A, B,C or D) is

Awa rd's ROM BIOS provides a built-in Setup progra m which a llows user modify
the system configura tion a nd ha rdwa re pa ra meters. The modified da ta will be
stored in a ba ttery-ba cked CMOS RAM, so da ta will be reta ined even the system

The "LOAD SETUP DEFAULT" is recommended in your first time setup this
