5. MAKING YOUR HARDWARE COMPATIBLE WITH MS-DOS 5.0
5.1 Acer 1100/33 and CTRL+ALT+DEL
If you have an Acer 1100/33 computer with an Award BIOS, you may not
be able to restart your system by using CTRL+ALT+DEL. Contact Acer for
a ROM BIOS upgrade.
5.2 Amstrad Systems and KEYB.COM
If your Amstrad system has a ROM BIOS version earlier than 1.4, and
you can't use your keyboard after loading KEYB.COM, contact your
vendor for a ROM BIOS upgrade.
5.3 Apricot Qi 386 Systems
If your Apricot Qi 300 fails to start while loading EMM386.EXE,

Some Apricot Qi660 and Qi900 computers may not work if MS-DOS 5.0 is
loaded into the high memory area. Run MS-DOS 5.0 in conventional
memory, or contact Apricot Computers for more information.
5.4 Arrow Keys and QBasic/MS-DOS Editor
If you can't use the arrow keys on your numeric keypad when running
QBasic or MS-DOS Editor, a memory-resident program named FIXSHIFT.COM
may help. To obtain FIXSHIFT.COM, call Microsoft Product Support
Services; see your registration card for the phone number.
5.5 AT&T Computer with an VDC 750 Display Adapter Card
Before using the MS-DOS Shell Task Swapper on an AT&T computer with a
VDC 750 display adapter card, remove the DEVICE=EGA.SYS command from
your CONFIG.SYS file.
5.6 Commodore PC III and Task Swapper

If you can't use your Nth, Procomm, or Sysgen external floppy disk
drive, contact your vendor for an update.
5.10 Hardcard II
If you can't use Plus Development Hardcard II or Hardcard II XL when
running EMM386.EXE, specify the exclude (x=) switch to prevent EMM386
from conflicting with the card's BIOS address.
See your Hardcard II manual to determine the BIOS addresses that
Hardcard II or Hardcard II XL uses. See the "MS-DOS User's Guide and
Reference" for more information about the exclude switch.
5.11 NCR VGA BIOS

running MS-DOS Shell or QBasic, see your NCR manual for information
about making your VGA BIOS PS/2 compatible.
5.12 Olivetti System with a CGA Video Board
An Olivetti system with a CGA video board may not scroll correctly.
Add the /s switch to the DEVICE=ANSI.SYS command in your CONFIG.SYS

If you use an XGA display with EMM386.EXE, you may need to exclude
certain memory ranges with the EMM386 EXCLUDE option (x=). To
determine which memory ranges to exclude, use your reference disk to
view the memory map.
5.18 Zenith Computer
To use the GRAPHICS command with a Zenith computer, set the STACKS
command in your CONFIG.SYS file to at least STACKS=9,256. For
information about the STACKS command, see Chapter 14 of the "MS-DOS
User's Guide and Reference."
