Win95 DOS Call: Difference between revisions

Windows '95, while not precisely a disk image utility itself, gives a programmer an easy access method for reading and writing data from/into disk image files. This comes from the total lack of security features in Win95. The method is the DOS interrupt call: INT21h, ax=0x7305. This might make Win95 a better choice for an OS development platform than Win98.

 

 

Set si to 0x6001 for a write, or 0 for a read. cx = 0xffff, ds:bx points to the DISKIO structure, dl = logical drive letter (1= A, 2= B, ... ), ax = 0x7305. Then do an INT 0x21.
