int13h emulation for fasm dos source. made for BIOS int13h tests via a virtual drive. compiles in 864 bytes. to use this code, include int13h in your source. call newint13h before to use the virtual drive call oldint13h before to exit the program the source includes: DOSread and DOSwrite fptr is just a structure declaration fd0.asm, hd0.asm and hd1.asm 18/nov/2010 for the moment, only drive0 = "c:/fd0.bin" is working. the other drives numbers and assignations don't work at all and if it pass over drive 80h, it bugs, maybe due to OS use that needs to use int13h to access to drive 80h... maybe... enjoy! edfed
