There are difficulties in using SYSGEN with a non-DRI CCP on the Model 4. It seems that SYSGEN looks for a checksum and will not accept Z80CCP or ZCPRx. The solution is to write a program that will overlay the original system with the new CCP or to extend Z80CCP with an in-memory-loader which will move Z80CCP to it's location. Problems with the new 48K-BIOS might result from the fact, that the newly generated BIOS contains the same drive parameters as the original version, 2 physical drives SSSD 40 Trk. If you have installed other drives, the original BIOS wouldn't recognize them. You must then insert a MM SYS DISK containing CONFIG.COM into A: and configure the new System to a freshly formatted disk, I missed the details. For information about about a better (banked) BIOS and ZCPR33, support for 80-Micro 320 K RAM etc., mail me your hardware configs. ------------------------------------------------------------------------------- Ruediger Soerensen, University of Mainz, W.
