Comments

This function attempts to reboot MS-DOS from drive C. If this fails, the user
is asked to insert a system disk.
This reboot is somewhat quicker than a Ctrl-Alt-Del or power-on reboot, as
it bypasses memory checking and reset operations (such as regenerating
the equipment list) normally performed during a reboot.
Warning: It is recommended that you do not use the Reboot interrupt if
there are TSR (Terminate and Stay Resident) programs installed. Some
TSR programs "hook" the Interrupt vectors. Hence using the INT 19H
function may result in the unit crashing.
Note: The MP2500 BIOS includes a boot menu that can be used to change
how the system boots (e.g. if the operating system is not present on drive
C) and can also be booted from a suitable diskette on a PC. For details, see
Chapter 9, Troubleshooting, in Part 2.
