.SH "DESCRIPTION"
.PP
Make a BIOS call that does only returns one value, or just status.
If there is an error, then the error code is returned in AH
(bits 8-15 of eax) and this function returns non-zero. This is
used for simpler BIOS operations. This call may hold interrupts
off for a long time on some laptops.
