LILO boot problem

LILO boot problem

Post by Uwe Schuerka » Fri, 04 Apr 1997 04:00:00



Dear netters,

recently I tried to setup a lilo boot config on a friends machine
(32mb intel 133, 2gb scsi, atapi CD). I told lilo to install
itself in the mbr of the first hard disk, and it looks like it
tries to go for the atapi cd-rom! The first line in lilo.conf
contained /dev/hda, so I changed that to /dev/sda by hand and
installed lilo again. Upon boot the lose95 partition would no
longer boot up, claiming some "I/O error" on the dos partition.

Currently we're booting linux off a linux boot disk, but of course
we'd like to run it off the hd to get rid of the floppy.
Is having an 1.5gb primary dos partition on /dev/sda1 a problem?
The controller is an AHA2940 if this matters.

Thanks in advance for any help,

        Uwe

LILO boot problem

<HTML><BODY>
When using LILO to boot from a large hard drive &gt; 1024 cyl. you can
run into a problem booting. Prior to loading the kernel you are at the
mercy of bios. If you have a drive larger than 1024 cyl. then you must
load your kernal from a partition that compleatly resides in the lower
1024 cylinders.
<BR>
<BR>To avoid this problem I alway create a small partition on the first part
of the drive big enough to contain all my kernal images and files from
/boot. I usually make this 4-10MB&nbsp;
<BR>
<BR>When I have booted from diskette I rename the /boot directory, make a new
dir called /boot , mount the small partition at /boot then copy the files
from the old renamed /boot dir to the newly mounted partition at /boot.
<BR>
<BR>I then copy my image file(s) to /boot. edit lilo.conf to point to the kernel
location and run lilo.
<BR>
<BR>remember to edit the fstab if you want the /boot partition mounted automatically.

1. Lilo boot problem: doesn't boot dos (invalid media type)

Hi,
I installed redhat 3.0.3 on my second eide hard drive. Initially I put
lilo on a floppy and it was working fine. Today I decided to reinstall
lilo on my first hard drive (master). When rebooted it could not start
windows 95. The following list tells what I did to recover and what did
not work in order.
1. boot dos from floppy
   fdisk /mbr did not work
   sys c: gave invalid media type error.
   using fdisk I viewed the partition tabel and the system was UNKNOWN

2. boot with lilo floppy to linux
   mount -t msdos /dev/hda /mnt
   ls /mnt
   gave invalid file type error.

3. I tried lilo -u but no luck.
   same problems as above: both linux and dos could not read the c drive

4. I copied boot.0300 to /dev/hda
   now linux could see some files but with weird names in my c drive

5. I rebooted without floppy and I got invalid system disk error.

Now the situation is linux can see some files with weird names and dos
gives invalid media type error.

Any help will be appreciated.
