So when will people be able to escape the 1 Meg address limitation of
MS-Dos and Microsoft C on the IBM PC/AT? Yes I know you can use bank switching
techniques. But that continues the brain damaged traditions of the IBM PC in
general.
I want to port code from other systems that need a large linear address
space to talk to frame buffers and other large arrays of special memory.
MS-Dos does not let you easily generate 24 bit addresses with the already
architecturally crippled 80286. Microsoft C's concept of pointers does not
allow a pointer to memory greater than 1 Meg.
So now I have to go thru a large detour just to get things to work...
When is IBM and Microsoft going to get it toghether and at least simulate
a real computer with a large address space?
In Frustration,
