- BOARD REVISION: All: B2 and C1
- DATE: 3/3/94
- RELEASED BY: Documentation Control
- SUBJECT: AMIBIOS Setup Option Constraints for the Series 75
-
-
- Users of all revisions of the series 75 should be aware of the following
- constraints in using the AMIBIOS Setup Program.
-
- 1. ADVANCED CMOS SETUP
-
- The 0E0000- 0EFFFF memory address is NOT available for adapter cards . This is
- used by the system flash BIOS. The option for Adaptor ROM Shadow E000, 64K
- should be DISABLED.
-
- 2. ADVANCED CHIPSET SETUP
-
- Do not use the WR-Thru setting for the DRAM Region B Control Mode option. The
- BIOS default is DISABLED. In this case the DRAM will be continuous. The
- other available setting is HOLE.
-
- The HOLE setting can be used to define a hole in the board DRAM region. The
- hole starting address and size can be defined using the settings in the DRAM
- Region B Size option and the DRAM Region Base Address option. This address
- "HOLE" will be reserved on the VL/ISA bus for adapter cards to use.
-
- If the HOLE setting is used, make sure your Operating System is configured to
- recognize the hole, and still use any DRAM present beyond the hole.
