I've refurbished a Z-100 (dual processor 8088 & 8085 S-100 system). I've got CP/M 85 and MS-DOS running on the hard drive. I would like to get CP/M 86 running from the hard drive as well. I can boot from a floppy disk and then use the hard drive. There is a BOOT217 program that might write a boot sector, but it only tells me "memory not available". Can anyone provide some guidance on how to boot CP/M 86 from a hard drive?
