HOW TO USE THE SYSBOOT DISK IMAGE
by Scott Stone <sstone@turbolinux.com>
for TurboLinux 2.0
----------------------------------
This document explains the usage of TurboLinux's sysboot.img file.
This disk is used to boot your system if LILO has become corrupted or
if LILO will not work with your system. If your system boots from a
SCSI partition, you will need one of the following SCSI adapters to
use this disk:
* Adaptec:
AHA-152x (ie, Zip ZOOM card)
AHA-1542
Cards with the aic7xxx chipset, ie AHA-2940
* BusLogic (any model, incl. FlashPoint series)
* AdvanSys (any model)
* AM53/79 C974 cards (ie, AMD-based Tekram cards)
* NCR 53c8xx cards (ie, NCR-based Tekram cards,
Diamond Fireport)
* Future Domain cards (16-bit ISA and PCI)
If you need a sysboot disk for a different SCSI adapter, email
sstone@turbolinux.com and let me know, and I can put one together for
you. Not all of the SCSI drivers can peacefully co-exist in the same
kernel, which is why some have been left out of the standard
sysboot.img.
Here's how to make and use the floppy image (from DOS):
1. Get a blank, formatted 1.44MB 3.5" diskette.
2. Put it in the 3.5" drive (we'll assume it's your first floppy
drive)
3. Use the 'rawrite' utility (in the 'dosutils' directory on the CD
or on the FTP site) to write sysboot.img to the floppy disk.
4. Use the 'rdev.exe' program (also in 'dosutils') to set the
partition ID that contains your Linux root filesystem (ie /dev/hda3,
/dev/sdb2, etc).
5. You now have a boot disk that you can use to start Linux!
Here's how to do it from a running Linux system:
1. Same as #1 above.
2. Same as #2 above.
3. Assuming that 'sysboot.img' is in the current directory, do:
'dd if=sysboot.img of=/dev/fd0'
4. Assuming that you want the disk to boot the Linux system on
/dev/sdb1, do:
'rdev /dev/fd0 /dev/sdb1'
5. You now have a boot disk that you can use to start Linux!
