Memory Hole At 15M-16M
In order to improve system performance, certain space in memory can
be reserved for ISA cards. This memory must be mapped into the
memory space below 16MB. When enabled, the CPU assumes the 15-
16MB memory range is allocated to the hidden ISA address range
instead of the actual system DRAM. When disabled, the CPU assumes
the 15-16MB address range actually contains DRAM memory. If more
than 16MB of system memory is installed, this field must be disabled
to provide contiguous system memory.
AGP Aperture Size (MB)
This field is used to select the size of the system RAM that can be
allocated to the AGP for graphics purposes. Aperture refers to a
portion of the PCI memory address range that is dedicated for the
graphics memory address space. Host cycles that hit the aperture
range are forwarded to the AGP without any translation.
On-Chip Frame Buffer Size
This field is used to select the frame buffer size.
Panel Type
Panel 1 640x480, one channel LVDS (A0-A2) for 18-bit panels
Panel 2 800x600, one channel LVDS (A0-A2) for 18-bit panels
Panel 3 1024x768, one channel LVDS (A0-A2) for 18-bit
panels
Panel 4 1280x1024, two channel LVDS (A0-A3, B0-B3) for 48-
bit panels
If you are using one of the standard panels shown above, select the
appropriate option according to the type of panel that you are using.
Otherwise, please contact your dealer or sales representative for a
custom-made BIOS that will suit the panel that you are using.
