Here are some essential points to consider when installing/configuring
an MS-DOS 5.0 system:
Windows
- WINA20.386 must be in the root directory of the boot drive.
- VDDVGA.386 must be manually copied from the DOS disk to your
Windows\System directory and an entry made in SYSTEM.INI saying DISPLAY=VDDVGA.386 made.
If this is not done you will get a Video Device Conflict message when starting Windows in
high resolution mode.
- APRICOT.386 is required in SYSTEM.INI for Networked systems.
- Do NOT include the mono video area in any memory driver (i.e. b000-b800).
- On SCSI systems, a SMARTDRV.SYS, AHA1540.SYS /v386 /b:32, or ASPI4DOS.SYS
/w must be loaded in CONFIG.SYS.
- HIMEM.SYS and SMARTDRV.SYS must be the DOS 5 versions and not those
supplied with Windows. Check that the entry in CONFIG.SYS is similar to
DEVICE=C:\DOS\HIMEM.SYS.
- Standard DOS 5 installation puts the line FILES=10 in CONFIG.SYS, this
must be increased to 20 or more, dependant upon what applications you are running.
On-Board Ethernet
- EMM386.EXE uses the same DMA as Apricot's on-board Ethernet and will
disable any network connection.
Qi 386-25, Qi 600 or Qi PCi machines
- APRA20.SYS must be loaded otherwise you will experience intermittent
hanging. On Release 1 of the Apricot MS-DOS 5.0 disks, version 1.00 will not load. Please
use APRA20.SYS from the bulletin board or Release 2, version 1.01. This must be the first
DEVICE= line in CONFIG.SYS.
LAN Manager 2
- The 'Microsoft LAN Manager Supplemental Information' manual, pages 27/28,
says that MOUSE.COM must be loaded after Netstart. As Apricot only supply MOUSE.SYS then
this can be done by using AMLOADDV /L C:\DOS\MOUSE.SYS which will load the driver from
DOS.
MS-DOS Memory Drivers
- APRUMB.SYS does not require HIMEM.SYS to be loaded, but if himem is to be
used (required for Windows 3 in enhanced mode and loading the DOS System high) then it
must be loaded before APRUMB.SYS.
- EMM386.EXE requires HIMEM.SYS to be loaded first.
- Until an Upper Memory Block manager (EMM386.EXE or APRUMB.SYS) has been
loaded, statements in CONFIG.SYS must be the normal DEVICE= not DEVICEHIGH=.
