Grub forces you to press arrow keys until the curser is over the desired option. I put the FreeBsd boot selector into the MBR and for Linux Grub or Lilo into a primary or extended slice (partition). -Hanspeter ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You have to edit the source. If you know the hex for the partition type
then it's reasonably easy. Below is a simple patch that adds 0x7 (my
NTFS/Windows) and recognises it as DOS. Done out of curiosity, more
than anything.
(From memory...)
cd /usr/src
patch {patchname}
cd sys/boot/i386/boot0/
make
make install
boot0cfg -B -o packet /dev/{your disk}
Be warned that the final boot0cfg has to be 512 bytes so if you add a
string it may become longer. I haven't tested my patch for the serial
console boot. The patch incorporates taking out the bell on
non-serial-console boots as well (pinched from somewhere else, now
forgotten) -- it was just annoying. The patch comes with no warranties,
but it's working for me. (I don't promise either that including it here
won't bu**er up the spaces/tabs).
Of course, once you applied and rebuilt you have to write it to your
boot sector. Man boot0cfg and don't forget -o packet if your partitions
go past cylinder 1024. And have a FreebSD boot CD handy so you can
rewrite with a standard one if this doesn't work!
The final problem is that if you use cvsup it will trash all over any
source changes you make when you next run it. Doing anything about that
seems more complicated than can be justified for a small number of
patches so I just keep them in a separate dir an re-apply them whenever
I need to. In this case, it will be just after I reaslise that I've
installed a beeping boot manager again :-)

PS just spotted the -m flag to boo0cfg for the first time. Amazing what
you find when you read the man pages :-)

This option causes MBR code to be replaced, without affecting the embedded slice table. I don't need to install it. -b boot0 Specify which `boot0' image to use. The default is /boot/boot0 which will use the video card as output, alternatively /boot/boot0sio can be used for output to the COM1 port. (Be aware that nothing will be output to the COM1 port unless the modem signals DSR and CTS are active.) I don't need to specify the boot image. -d drive Specify the drive number used by the PC BIOS in referencing the drive which contains the specified disk. Typically this will be 0x80 for the first hard drive, 0x81 for the second hard drive, and so on; however any integer between 0 and 0xff is acceptable here. I don't need to specify the drive. -f file Specify that a backup copy of the preexisting MBR should be writ- ten to file. This file is created if it does not exist, and replaced if it does. I don't need to make a backup copy. -m mask Specify slices to be enabled/disabled, where mask is an integer between 0 (no slices enabled) and 0xf (all four slices enabled). The correct slices are already enabled. The system boots fine to either OS. -o options A comma-separated string of any of the following options may be specified (with ``no'' prepended as necessary): The default options are being used, and I see no reason to change them. packet Use the disk packet (BIOS INT 0x13 extensions) interface, as opposed to the legacy (CHS) interface, when doing disk I/O. This allows booting above cylinder 1023, but requires specific BIOS support. The default is `nopacket'. setdrv Forces the drive containing the disk to be referenced using drive number definable by means of the -d option. The default is `nosetdrv'. update Allow the MBR to be updated by the boot manager. (The update Allow the MBR to be updated by the boot manager. (The MBR may be updated to flag slices as `active', and to save slice selection information.) This is the default; a `noupdate' option causes the MBR to be treated as read- only. -s slice Set the default boot selection to slice. Values between 1 and 4 refer to slices; a value of 5 refers to the option of booting from a second disk. The default slice is determined by the last boot. I see no reason to change that. -t ticks Set the timeout value to ticks. (There are approximately 18.2 ticks per second.) The timeout is set to 10, and I see no reason to change that. -v Verbose: display information about the slices defined, etc. Self-explanatory. So where is the switch that I use to edit the menu?
