I came to know the dosemu reserves A000 segment reserved for graphics. Is it possible to shift OR change another segment for graphics.
Ralf Brown memory.lst states: --------V-MA0000000-------------------------- MEM A000h:0000h - EGA+ GRAPHICS BUFFER Size: 65536 BYTEs
So it was always there. QEMM have a program called "vidram", which allows to use that region as a base memory by the cost of not being able to diplay graphics, but vidram will not work under dosemu because qemm itself doesn't work under dosemu.
Is it logically correct.
But how are you running your program at a pure dos at first (i.e. not under linux/dosemu)? If your program works only with QEMM's vidram or something similar, then your program is broken at a first place. Dosemu allows you to use both UMB and HMA, so there should be no disadvantages against the pure dos (except that QEMM with all its wonderfull tricks can't be used).
and running a cobol application.
I don't know what cobol was used, but if it is a MicroFocus cobol, they provide a DOS extender for it called xm, wich will let the program to use all the memory available for DPMI. Increasing the base memory above 640Kb is definitely the bad idea, as it is used very rarely even in a pure DOS and will cost you the inability to display graphics. - To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
