INT 15 U - Tandy 1000 Model ??? - SET ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. PAGE AX = 7003h DL = ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. page to be mapped at 0E0000h (0-6 (13?)) Return: CF clear if valid ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. page specified Note: Some Tandy machines have DOS and DeskMate in a 512k paged ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs.. The BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. uses this call to map ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. pages in the 64k segment at 0E0000h. The 1000TL has 8 64k ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. pages; page 7 is permanently mapped at 0F0000h. There may be 16 32k ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. pages on other systems. SeeAlso: AX=7002h,INT E0"DeskMate"
