He can't find the correct root partition, pass the correct root=
parameter as he said, or fix it in the grub configuration. You still
have the old kernel, don't you?

"He can't" compile in the correct filesystem (ext3) support, you mean.

Recompile, this time with ext3 support.

You might need to compile ext3 into the kernel and not as a loadable
module.
 
 
 

1. Help! Kernel panic: Unable to mount root fs??

Hi there,
        I have problem in booting my Linux system after the
        installation.  I have tried the slackware and the
        redhat linux (Dec 1996) with no luck.

        The linux boot up process reports

        " 03:02: rw:0,want=2, limit=0
          EXT2-fs: Unable to read superblock
          attempt to access beyond end of device
          FAT bread failed.

        The above message repeats with the EXT2-fs replaced
        by MINIS-fs.

        The last message is
        "isofs_read_super: bread failed, dev 03:02 iso_blknum 16 block 32
        Kernel panic: VFS: Unable to mount root fs on 03:02"

        What's that mean? and why can't I mount root fs?

        My system configuration is
        "486 AMD-5x86-133, 16MB RAM, 1 540MB IDE harddisk"
        I have used IDE cache controller and my CMOS setup for
        the hardisk type is "1" which allow the cache controller
        to autodetect the harddisk.

        The cache controller detected "1048C, 16H, 63S" for my harddisk.

        My harddisk partition is

        For Dos : 1st 150MB
        For Linux : 1st 30MB for /
                    2nd 300M for /usr
                    3nd 16MB for swap

        Any suggestion to cure my problem is highly appreciated :)
        Thank you very much

                                                        Dominic
