Husky MP2500 Manual page 374

There are a number of ways to improve FS/2 compatibility:
• MP2500 and FS3 are normally provided with MSDOS 6.22 installed, but
as a special option, can be supplied with the same DOS version as FS/2
(3.30a).
• You will probably need to rewrite any code that uses FS/2-specific
features.
• Remove any FS/2 code used to address comms issues such as direct
access to the UARTs in native mode for speed - this is neither needed
nor supported on MP2500 or FS3.
The FS/2 private system RAM has been retained in full on MP2500 and
FS3, with all FS/2 locations still valid, so that code that relies on in-depth
knowledge of these locations will still function.
The AT compatibility issue can be addressed in one of two ways:
• MP2500 and FS3 can be configured as an XT-class machine, so that
the INT 15H conflict does not arise.
• MP2500 and FS3 INT 15H functions could be relocated so that the
conflict does not arise.
Contact your system supplier or WPI H
details.
