Can't open root device 08:04


Unable to load Linux-Mandrake 6.1 (Red Hat Linux with enhancements) on a new computer and vacant HD. Last four lines on boot attempt as follows.
Partition check:
hda :hda1
VFS: Cannot open root device 08:04
Kernal panic :VFS :unable to mount root fs on 08:04

What am I doing wrong??

Partitions are screwy ... speak to us of your partitions.

Device 08:04 is the fourth partition on a scsi hard drive. I take it you do not have one thus the panic. Now - does this occur while booting the install disk when you try to install, or did you already install and this is the first boot to the new installation?

If the latter - you need to edit the bootloader config file (grub.conf or lilo.conf) to have a root=/dev/hda1 (I'm guessing the actual place you stuck root here.) option. You may be able to pass this option to the kernel at the bootloader prompt. Otherwise, you'll need to boot into rescue mode using the install disk, and edit from there.

root device 08:04

Thanks for the info, however it would not work. I finally loaded LinixMandrake6.5 CD 1 & 2 then, Dos-Ms StartUP floppy. Changed directory to d:\ then used AUTORUN to get the thing to boot. Everything seems to work except for shutting down, have to use the power button.

Can find no place to type \sbin\halt, halt or use the stop command as my screens are much to large (icons are approx 1.5"), only eight lines of test fit on a screen??
Have tried everything in the USER GUIDE, unable to figure-out how to change the resolution... any suggestions??
I have tried GNOME,KDE,DEFAULT,ANOTHERLEVEL and one more that has left my short memory while typing this lengthy question.
I'm using a LANPARTY 250GB motherboard-NVIDIA gFORCE 5700VE 250mb video card-with a 17" color TFT LCD monitor capable of 1280x1024 at 75Hz.
To further confuse this issue all 3 work fine on my WINDOWS XP. have it set to 800X600 at 72Hz in WINDOWS for best size and resolution.

I have somewhat a dual boot system using a Romtec TriosIII switch to completely isolate my three HD's

You are booting linux from DOS?!

It sounds like you are messing up the installations there ... surely you installed mandrake as a dual boot with windows - specifying GRUB or LILO as your bootloader in the master boot record. When you next power up, the bootloader gives you a choice of OS's.

To change the screen resolution - in gnome, click on start icon and go to system settings > display ... this dialog can change the screen resolution for you. However, if it is bad as all that you may want to reboot, passing the "resolution=640x480" command to the kernel. From there you should be able to see what you're doing.

However, I have no idea how you would get this command to the kernel is you boot from d:\autorun ???

(BTW: the backslash "\" dosn't work in linux - hmmm except for some live cd's I guess.)

However - if I were you I'd do a complete reinstall from scratch.
(Tell me if you did any of this...)
1. Set the BIOS boot-order to boot from CD first off.
2.Boot with the installation CD1 in the drive
3.Follow the installer options to make a dual boot machine - you will need to partition your second hdd (called hdb) into three parts (hdb1 = ext3, mountpoint /boot; hdb2=ext3, mountpoin /; hdb3=swap) Allow 128Mb for swap and boot and the rest is root (/).
4.Select Mandrake as your default boot in the bootloader

When you've finished configering everything, hit finish and the installer does the rest. Then it will boot your right into linux no trouble. Don't try anything fancy this time.

Find some lines of text located somewhere, somehow??

(: FontPath set to "unix /:-1"
(- -)SVGA: PCI : NVidia Unknown chipset
(0x0344) rev 161, Memory@0xe8000000, 0d0000000
(- -)SVGA: chipset: generic
(- -)SVGA: videoram: 64k
(**)SVGA: clocks: 25.18
(**)SVGA: Using 8bpp, Depth 8, Colorweight 666
(- -)SVGA: Using builtin driver modes
(- -)SVGA: Built Mode : 320x200
(- -)SVGA: Virtual resolution set to 320x204
(--) SVGA: SpeedUp code selection modified because virtualX != 1024

It is very difficult to navigate in a window with that resolution. Could you give a specific location for the GNOME start button or a different approach to resolution correction?
On the GNOME desktop I can see 9 folders: one is the System Icon with 7 sub-folders;About Myself, Change Password, Control Panel, Disk Management, GnoRPM, LinuxConf, TimeTool.
Another is the Settings Icon with 9 sub-folders; GNOME Control, Desktop, Multimedia, Peripherals, Mime Types, URL Handlers, Lmlib Configuration, Default Editor, Menue Editor.
I find nothing an any folder about screen resolutions.
When I power up I go to a LILO boot, with three choices. Wait 5 sec for automatic (default) boot, or Linux<enter>, or Linus-up<enter>. All three give the same result--Wrong resolution.
In frustation I have tried to do a new install from scratch...Same results as my original posting. Instead of a few lines, this is the last page durring those attempts..

VFS: Cannot open root device 08:04

Maybe this will shed more light on my delima. I don't enjoy typing, I hope there is no errors. Should I just give in again?????

Please don't laugh at the next statement..

I have (from Scratch) built five computers. One each 3.1-win95-win98 and two winXP's and have had difficulty along the way. It was however enjoyable.
On each of these computers I made an attempt to install Linux..??? I almost hate PENGUINS.
I am tired of looking at (THE COMPLETE LINUX OPERATING SYSTEM 6.5) package sitting in my computer desk. If you think it is a lost cause just let me know, I'll give in one more time.., have close to 2wks on this last attempt but hate to give in.

Everything seems to works fine -- just can't see it.
