SETUP.EXE Vr 1.2.6 on XEN-S
This, and any subsequent versions, will refer to base memory in
quantities of 1MB on XEN-S machines. (This does not apply to older XEN-i systems).
"Base Memory" now refers to the total motherboard memory
whereas "Extended Memory" refers to any memory added via the expansion slots.

Normal BIOS |

BUS and BIOS Speed in SETUP.EXE
The normal IBM memory map includes the ROM BIOS copied into RAM above
640K on boot-up. Apricot have built a routine into the BIOS to stop this occurring, thus
allowing the memory to be available as Extended Memory. The BUS speed refers to the
expansion slot bus, and swaps Normal at 8MHz to Fast at 10MHz; a number of third party
cards will not run above 8MHz.
If on a 1MB system you require use of Extended Memory, you must set the
BIOS speed to normal. If you are using AMLOAD to load network drivers into memory between
640KB and 1MB, you must set the BIOS speed to Fast, options 1 or 3.
The options you are given are :
| 0 |
Normal BUS and BIOS |
1 |
Normal BUS Fast BIOS |
| 2 |
Fast BUS Normal BIOS |
3 |
