I have a load of Slackware 14.0 64-bit sharing a Windows drive, dual boot. But I kept running out of space on my Linux partition. So I installed another hard drive, 100GB, and installed Linux on that drive with the Windows/Linux dual boot and files drive (an additional hard drive with files) disconnected. I had problems with a Kernel panic VFS errors, "VFS: Cannot open root device "803" or unknown-block(8,3)". I believe I got it to work with the drive by itself, without the other drives connected. So I then reconnected all of the drives and basically fought with it and fought with it, trying to get it to work, because I was getting the kernel panic errors after doing that. But gradually I made progress until I'm where I am now. This is basically it and the steps I take:
1. I boot to the hard drive, I get kernel panic errors, "VFS: Cannot open root device "803" or unknown-block(8,3)"
2. So I boot to the Slackware DVD, mount my Linux drive (all the other drives are connected as well, but not mounted).
3. Go to Setup and run the Slackware installation script for Lilo.
4. Do Expert, Begin - Start with new LILO header and choose /dev/sda1.
5. On the Linux setting, I choose the Linux partition.
6. On the Windows option, I select where my Windows is.
7. Then select the 4 option to Install. It installs with no errors.
Here is the problem, I reboot my PC and press F11 for my BIOS boot selection and choose the drive with Linux on it, the slackware boot screen comes up, and I choose Linux. Here is the weird part, unless I keep the CD in the DVD drive, I get a kernel panic error. But if I leave the Slackware DVD in, most of the time it boots fine. But take out the DVD and it will fail with the kernel panic and VFS: Cannot open root device "803" or unknown-block(8,3)"
I am currently logged in because at boot: I entered "huge.s /dev/sda1 init= ro" Something like that, I can't remember exactly, I'm new to this, but I'm pretty sure that is it because here I am, booted fine. Here is my lilo.conf file:
# LILO configuration file
# generated by 'liloconfig'
# Start LILO global section
# Append any additional kernel parameters:
boot = /dev/sda1
# Boot BMP Image.
# Bitmap in BMP format: 640x480x8
bitmap = /boot/slack.bmp
# Menu colors (foreground, background, shadow, highlighted
# foreground, highlighted background, highlighted shadow):
bmp-colors = 255,0,255,0,255,0
# Location of the option table: location x, location y, number of
# columns, lines per column (max 15), "spill" (this is how many
# entries must be in the first column before the next begins to
# be used. We don't specify it here, as there's just one column.
bmp-table = 60,6,1,16
# Timer location x, timer location y, foreground color,
# background color, shadow color.
bmp-timer = 65,27,0,255
# Standard menu.
# Or, you can comment out the bitmap menu above and
# use a boot message with the standard menu:
#message = /boot/boot_message.txt
# Wait until the timeout to boot (if commented out, boot the
# first entry immediately):
# Timeout before the first entry boots.
# This is given in tenths of a second, so 600 for every minute:
timeout = 1200
# Override dangerous defaults that rewrite the partition table:
# VESA framebuffer console @ 800x600x64k
vga = 788
# Normal VGA console
#vga = normal
# Ask for video mode at boot (time out to normal in 30s)
#vga = ask
# VESA framebuffer console @ 1024x768x64k
# VESA framebuffer console @ 1024x768x32k
# VESA framebuffer console @ 1024x768x256
# VESA framebuffer console @ 800x600x64k
# VESA framebuffer console @ 800x600x32k
# VESA framebuffer console @ 800x600x256
# VESA framebuffer console @ 640x480x64k
# VESA framebuffer console @ 640x480x32k
# VESA framebuffer console @ 640x480x256
# End LILO global section
# Windows bootable partition config begins
other = /dev/sdc1
label = Windows
table = /dev/sdc
# Windows bootable partition config ends
# Linux bootable partition config begins
image = /boot/vmlinuz
root = /dev/sda1
label = Linux
# Linux bootable partition config ends
Also, it may work the first reboot after running the LILO script from the DVD the first time, but even with the DVD in the drive upon reboot, I get the error again. The only thing I can think of that is causing the problem is that the mounting of the DVDROM drive is making the mapping out of wack and it confuses LILO. Thanks for your help.
