Product Description
The ABHiQV daughtercard is capable of being used with the B65555 and B69000 graphics controllers.
The B65555 is designed to be used with EDO DRAM whereas the B69000 has 2MB of SDRAM embed-
ded within the controller and does not use external DRAM components. Both combinations of controller
and memory can be accommodated by the ABHiQV daughtercard.
The design kits for these products in the PCI bus environment all use a common board known as the
DKHIQV-PCI Board. The ABHiQV daughtercard containing HiQVideo Controller is installed onto the
DKHiQV-PCI board to complete the design kit. This User’s Guide describes the ABHiQV (Fab. Rev. C)
daughtercard.

Installation
3.1
General Overview of the Setup Process
The ABHiQV daughtercard is normally shipped with a VGA BIOS EPROM already installed (U2; refer
to Figure 1). This BIOS has been programmed to support a limited set of resolutions and is intended
primarily to allow a CRT monitor to display the system status as the system boots up.
To set the VGA BIOS and drivers for a specific flat panel, the user must use the CHIPS BIOS Modifica-
tion Program (BMP) to configure the VGA BIOS (usually a RAM-loadable BIOS) to match the specifica-
tions of the panel. Refer to the corresponding CHIPS BIOS and driver user’s manual for details of how
to use the BMP. There is no need to remove or modify the pre-installed VGA BIOS EPROM when using
a RAM-loadable BIOS.
It should be verified that the DK board works correctly with a CRT interface using the pre-installed VGA
BIOS ROM before attempting to install a flat panel.
