I'm a bit of a n00b when it comes to Linux, but something I'd been wondering about for a while was CFLAGS settings, and whether I could make anything run better. After recompiling BM and re-running it, it made little or no difference (marginally slower, but within margin of error). Not to daunted I wondered about recompiling the 2.4.26 kernel, just changing -O2 up to -O3 in Makefile. Recompiled and setup, and was rather surprised at the speed increase!

volcheck

volcheck(1)							   User Commands						       volcheck(1)

NAME

       volcheck - checks for media in a drive and by default checks all floppy media

SYNOPSIS

       volcheck [-v] [-i secs] [-t secs] pathname

DESCRIPTION

       The  volcheck  utility tells Volume Management to look at each dev/pathname in sequence and determine if new media has been inserted in the
       drive.

       The default action is to volcheck all checkable media managed by volume management.

OPTIONS

       The following options are supported:

       -i secs	Set the frequency of device checking to secs seconds.  The default is 2 seconds.  The minimum frequency is 1 second.

       -t secs	Check the named device(s) for the next secs seconds.  The maximum number of seconds allowed is 28800, which is 8 hours.  The  fre-
		quency of checking is specified by -i. There is no default total time.

       -v	Verbose.

OPERANDS

       The following operands are supported:

       pathname        The path name of a media device.

EXAMPLES

       Example 1: A sample of the volcheck command.

       The following example

	       example% volcheck -v /dev/diskette
	       /dev/diskette has media

       asks Volume Management to examine the floppy drive for new media.

       The following example

	       example% volcheck -i 2 -t 600 /dev/diskette1 &

       asks Volume Management if there is a floppy in the floppy drive every 2 seconds for 600 seconds (10 minutes).

FILES

       /dev/volctl     Volume Management control port

WARNINGS

       Due  to a hardware limitation in many floppy drives, the act of checking for media causes mechanical action in the floppy drive.   Continu-
       ous polling of the floppy drive will cause the drive to wear out. It is recommended that polling the drive only be performed during periods
       of high use.
