Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I figured the newbie forum was best as I am clueless as to whether this is software, hardware, firmware, or tupperware ???
Anyhoo, I have a redhat 6.2-ish system ( kernel 2.2.21 - boggo std glibc) that runs fine from ide disc (/dev/hda) that I am trying to get working from a 9.1GB seagate scsi disc on a tekram 395uw controller.
I have rebuilt the kernel with the driver in so that I can use the scsi disk for data fs's (works fine) but cannot get the system to boot from the scsi.
I have made a copy of my ide root fs and put it on the scsi 1st partition ( cylinders 1-1023 = /dev/sda1) altered fstab (on the scsi disk) so that root is sda1 & other fs's /usr etc are still on /dev/hda? . Boot off a floppy (mkbootdisk) and do a "linux root=/dev/sda1" which works fine, then /sbin/lilo -L to put the boot info into the mbr for the scsi disk & when I boot I get the lilo: prompt & hit <return> & then get a screen full of 9's & it hangs ??
Lilo version is 22.3.4 (latest), disk is dos formatted first to get 1106/255/63 disk geometry. Bios disk numbers are ide = 0x80, scsi1 = 0x81 but bios is set to boot from floppy -> scsi -> ide-0
I have even pulled the ide disk completely so that only scsi remains ( system should still boot without /usr ) and I still get the screen full of 9's.
Could you post your lilo.conf? You say that you've put it in the MBR of your SCSI disk, but where does Lilo want to boot from? The first line of your lilo.conf file should say something like:
boot=/dev/sda (or something - I'm not at a Linux box to look).
tried /dev/sda ( boot from mbr ) - even tried /dev/sda1 (which i guess shouldn't work as there isn't anything else on the disk?) - both no sucess :-( . I thought originally it was that I had too many cylinders on my disc caused by a funny format - so I dos ( w95 vfat) formatted the disc to get 1106/255/63 . I used to get LIL- and now I get LILO: 9999999999999 etc etc. I have even tried defining the disks by the bios numbers but that didn't seem to help either.
maybe it's a specific hard ware prob - I have run the apps on the boot floppies from lilo & everything checks out. I am a bit stumped - maybe an email to john coffman ( the writer ) is the next step.
Will you be using your ide disks for anything else? If so, why not simply have it in the ide mbr, which presumably works fine, and have a Linux entry that points to sda? I'm sure there is a perfectly good reason for the errors you're getting, but if you're gonna have an ide disk around anyway, why hassle yourself and make things hard?
TRIUMPH !! - removed ide disc completely after replicating /usr, /usr/src & other filesystems on additional partitions on the scsi disk did a " cd /usr ; find ./ -print | cpio -pudmv /test1_usr " to fill up my scsi version of /usr , created some missing device files ( /dev/mouse !! ) , set bios to boot from scsi & tossed ide disc out of window.
System now boots & goes like the clappers.
