#### Patching a CP/M + disk

The following instructions show how to reconfigure the CP/M + on your Start of Day Disc so that it can access Drive B without calling RAMDOS+. Do not reconfigure your original System Disc.

These instructions are for use with a single disc drive, and it may be less confusing if you disconnect drive B while reconfiguring your disc.

Reset your computer by pressing CTRL-SHIFT-ESC simultaneously. Put your copy of the System Disc in Drive A, with Side A uppermost.

Type in the commands which are underlined, and follow the instructions in square brackets. The other words are the responses made by the computer.

You carry out the following procedure at your own risk. Although I have
checked this data, you should be aware that OCR errors may have slipped
through, and entering incorrect data will bugger things really spectacularly.
