DOS Workstations Memory Issue
(Maitre'D 2003)
Issue:
It is possible, depending on configuration, that a DOS workstation's
available conventional memory may be insufficient when running Maitre'D
2003.
Note: This affects many manufacturers' DOS products.
Symptoms:
This can cause problems with workstation operations, going as far as
freezing up, and with the proper functioning of peripheral devices, going
as far as failure.
Resolution:
Dealers who have already upgraded locations using DOS workstations to
Maitre'D 2003 should follow these steps to try to resolve this issue,
until they can update to the latest Service Pack:
Note: Dealers who will be upgrading current locations using DOS workstations
should first perform these tests on a demo system with the very same workstation's
model before attempting to upgrade your customer's restaurant.
- Upgrade the restaurant's data to Maitre'D 2003 with
the latest Service Pack.
- Redo all workstations' boot disks, and boot up all
workstations with these new disks.
- Available memory on a DOS workstation can be read
by typing 444 and [ENTER] at the server sign on screen. Perform this 444
memory test on the workstations to insure that your memory is above 22Kb.
- If memory is above 22Kb, you could upgrade the restaurant
to Maitre'D 2003, but do keep in mind that if future Service Packs could
use less memory, there is no guaranty that they will not need more memory
instead.
- If memory is below 22 Kb, and these are SHARP DOS
workstations, you might be able to resolve this issue by following the
instructions found in the "Maitre'D 2003 with SHARP DOS workstations
memory issue" document on the Maitre'D Knowledge base
- If available memory is below 22Kb, DO NOT upgrade
that restaurant to Maitre'D 2003 with these DOS workstations. Consider
updating to Windows XP Professional workstations, with Windows 2003 on
the Maitre'D server instead.
Note: Maitre'D will not be able to resolve some of these issues with
future Service Packs, as even Microsoft have dropped support of DOS along
with Windows 95 and NT.
