RAM DISK EMULATION

5.5

P r o g r a m m i n g T i p s

DOS 3.3’s Read/Write/Track/Sector routine, RWTS, can be used to directly read or write to the RAM disk. If you wish to use RWTS with the RAM disk, follow all standard protocols and do not call into RWTS; enter RWTS from the top of the routine. The standard or custom RWTS Input/Output Block (IOB) and its sector buffer must lie in the $200 to $BFFF area of main motherboard memory. Programs written to run in the language card area of memory must have their IOB table and sector buffet in the lower 48K main memory area.

Auxiliary 64K bank 0 Ia always in place. The only time other 64K banks are activated is when RWTS calls them.

DOS Updates

The DOS RAM disk software will be updated in the future adding new features. Some new features planned include a user re—definable slot option and a customization utility to allow you to modify the RAM disk itself.

Registered owners will be notified of updated RAM disk software.
