RAMDRIVE version 6 This is a public domain program that I have installed for use with the 256K RAM expansion. To use it you need to create a disk with a 63K version of your system :- A>MOVCPM 63 * A>SAVE 34 CPM63.COM A>SYSGEN CPM63.COM Then boot from that disk and to install RAMDRIVE just type:- A>RAMDRIVE This is the simplest way to use the RAM as a RAMDRIVE C:. CBIOSR is just a fairly standard Kaypro BIOS with no frills plus the routines from RAMDRIVE. Since I don't like being interrogated every time I cold boot I made the initialisation a separate program.
