<strong>BIOS (CP/M only)<strong>
==SYNOPSIS==
#includ <cpm.h>
char bios(int n, int a1, int a2)
==DESCRIPTION==
This function will call the n'th bios entry point (cold
boot = 0, warm boot = 1, etc.) with register BC (CX)
set to the argument a1 and DE (DX) set to the argument
a2. The return value is the contents of register A (AX)
after the bios call. On CP/M-86, bdos function 50 is
used to perform the bios call. This function should
not be used unless unavoidable, since it is highly
non-portable. There is even no guarantee of portability
of bios calls between differing CP/M systems.
