- XBIOS -- (C) Copyright 1988 Qualitas, Inc.
-
- This program should be used only on IBM PS/2, PS/2-compatible, COMPAQ
- 386S (the one with the 386SX chip), or any other machine which
- provides an Extended BIOS Data Area. IF YOU ARE NOT RUNNING ON ONE OF
- THE ABOVE SYSTEMS, DO NOT USE THIS PROGRAM.
-
-
- Purpose
- -------
-
- This device driver copies the Extended BIOS Data Area at 639 KB to low
- memory and frees the region from 639 to 640 KB. This relocation also
- allows multitasking programs such as Windows 2.03 and DESQview 2.01 to
- use this 16 KB of memory from 624 to 640 for program swapping.
-
- If you are running Windows 2.03 in conjunction with 386MAX, you *MUST*
- either install this device driver or tell 386MAX to INCLUDE=9C00-A000.
- By default 386MAX does not mark this last 16 KB page as EMS swappable
- because of the 1 KB hole at 639 KB. Windows 2.03 doesn't correctly
- handle the last page being absent, but it does correctly handle the
- hole. Thus you must either avoid the hole (with XBIOS.SYS) or include
- the page (with INCLUDE=9C00-A000).
-
- No memory is saved by this approach because the same area used at 639
- KB is copied into the device driver. However, the device driver's
- overhead is only 64 bytes.
-
-
- Installation
- ------------
-
- To install this device driver, copy XBIOS.SYS to your hard disk and
- place a line similar to the following in your CONFIG.SYS file:
-
- Device = d:\path\XBIOS.SYS
-
- where d:\path is the drive letter and directory containing the
- driver. Be sure to place the above line preceding 386MAX.SYS so
- 386MAX does not see any holes in the memory above it.
