.SH "DESCRIPTION"
.PP
\fBdo_probe\fR has the difficult job of finding a drive if it exists,
without getting hung up if it doesn't exist, without trampling on
ethernet cards, and without leaving any IRQs dangling to haunt us later.
.PP
If a drive is ``known'' to exist (from CMOS or kernel parameters),
but does not respond right away, the probe will ``hang in there''
for the maximum wait time (about 30 seconds), otherwise it will
exit much more quickly.
.SH "RETURNS"
.PP
0  device was identified
1  device timed-out (no response to identify request)
2  device aborted the command (refused to identify itself)
3  bad status from device (possible for ATAPI drives)
4  probe was not attempted because failure was obvious
