time-dependent, automatic boot switch?
Posted on 2004-09-15
Is the following possible?
If the time of day is within a certain range, then boot to CD. Otherwise, boot to HD. Do this *without* any user intervention (e.g. user removing the CD or going into BIOS).
BIOS can be set to adjust boot order.
bootable CD (my customized Knoppix 3.4) is always in the CD-ROM (never ejects).
a floppy drive exists.
Can't modify the HD in any way.
As far as I can see the options are 1) modifying isolinux on the Knoppix CD -- but how? 2) putting a bootloader on floppy and booting initially from that -- but if I put lilo or grub on a floppy they can't see the CDROM.
I have been puzzling over this for a while and would be very grateful for any ideas!
