==Introduction==
HDCPM is an Amstrad CPC application that enables your computer to boot and run CP/M Plus from a mass storage device. A maximum of four 8MB partitions or virtual disks can be used to make the vast amount of 32MB of data available to CP/M Plus.<br />
The RTC battery is depleted. The RTC driver will continue to operate
normally but the readings are not reliable. Replace the RTC battery.
