Procedure for installing software on a new K80 CF disk
Introduction
This is step-by-step procedure for installing software on a new CF disk for K80. The CF disk must be have a capacity of 32Meg or larger.
Format the new CF disk
A new CF disk must be format to CP/M file system. Caution: the formatting process will erase all files on the CF disk. The formatting is done with the “xX” command of the K80 Monitor as follow: Power on the board or press reset to run the K80 monitor. At the '>' prompt, type:
xA to format drive A
xB to format drive B
xC to format drive C
xD to format dirve D
Please note the drive letter (A/B/C/D) must be in upper case.
Installing CP/M 2.2 BDOS/CCP/BIOS
CP/M 2.2 BDOS/CCP/BIOS is installed in track 0 of the CF disk. At the K80 monitor prompt, load the Intel hex file 'cpm22all.hex'; after the file load is completed, type 'c2' to copy CP/M2.2 to track 0 of the CF disk. The command 'b2' will boot CP/M 2.2, but there are no files on the CF disk right now.
Installing XMODEM on CF disk
XMODEM.COM will be the very first file on the new CF disk. At the K80 monitor prompt, load the Intel hex file 'xmodem.hex'; after the file load is completed, type 'b2' to boot up CP/M 2.2 and then type 'save 17 xmodem.com' at CP/M prompt. This will save the xmodem.hex that's in the memory as a executable CP/M file in CF disk.
Loading software on CF disk
Once xmodem is installed, it is used to load all subsequent files into the CF disk. At the CP/M 2.2 prompt, type:
xmodem unarj.com /r/z1
This will first load a decompressing software, unarj.com, to the new CF disk. Then type at the CP/M 2.2 prompt:
xmodem cpm2.arj /r/z1
This will load the compressed CP/M 2.2 distribution files. After cpm2.arj is loaded, type at the CP/M 2.2 prompt:
unarj e cpm2
This will decompress the CP/M 2.2 distribution files. The CF disk is now ready for use.
