2.6 Expansion Slots (PCI, AMR, and AGI Slots)
There are 3 PCI slots, 1 AMR slot, and 1 AGI slot on this motherboard.
PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
Because the installed AMR card will occupy the same external
connecting position with the PCI card installed in “PCI3” slot, you will
no be able to install any PCI card in “PCI3” slot if an AMR card has
already been installed in the AMR slot.
AMR slot: AMR slot is used to insert an ASRock MR card (optional) with v.92
Modem functionality.
AGI slot: The AGI [ASRock Graphics Interface] slot is a special design that only
supports compatible AGP VGA cards. For the information of the compat-
ibleAGP VGAcards, please refer to the “Supported AGP VGA Cards List”

BIOS FWH chip on the motherboard stores the BIOS Setup Utility. When you start up
the computer, there is a chance for you to run the BIOS Setup. Press <F2> during the
Power-On-Self-Test (POST) to enter the BIOS Setup Utility, otherwise, POST
continues with its test routines.
If you wish to enter the BIOS Setup after POST, restart the system by pressing
<Ctl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis. You
can also restart by turning the system off and then back on.
The BIOS Setup Utility is designed to be user-friendly. It is a menu-driven program,
which allows you to scroll through its various sub-menus and select among the
predetermined choices.
Because the BIOS software is constantly being updated, the
following BIOS setup screens and descriptions are for reference
purpose only, and may not exactly match what you see on your
screen.
