625 bytes added, 14:46, 20 May 2018
/* Amstrad's implementation of CP/M+ */
* This program is loaded into RAM at &c00.
* This is then executed. (EMS contains the BIOS, BDOS and relocates and re-configures the memory. CP/M doesn't use the CP/M 2.2 BIOS from the Amstrad disc ROM.)
 
=== Creating a minimal boot disc ===
 
Minimal requirements are:
* 64KB ram
* system format
* CPM+ boot sector
* C10CPM3.EMS
 
Using CPM2.2:
* Use disckit2 to format a vendor format disc
* Use BOOTGEN to put the CPM+ boot sector onto your disc. (Source is CPM+, Destination is your disk).
* Use FILECOPY to put C10CPM3.EMS onto your disc (FILECOPY C10CPM3.EMS. Source is CPM+, Destination is your disk).
* Your minimal CP/M+ disc is bootable.
 
Using CPM3.3:
* Use disckit3 to format and install the boot sector onto the disc.
* Use PIP to copy C10CPM3.EMS to your disc (B:=A:C10CPM3.EMS)
* Your minima CP/M+ disc is bootable.
