Xandros 4.1 OS, AMD64 SATA disks.
menu.lst  - reads;

The LFS system is located in /mnt/lfs which is situated on/dev/sda7.

The following text is displayed when loading comes to a halt.

".......
Root - NFS: No NFS server available , giving up.
VFS: unable to mount root fs via NFS trying floppy
VFS: insert root floppy and press enter
...."

Floppy, prepared as in section 8.4, was inserted, pressed return.
The following text was displayed;
"
List of all partitions:
0200      1440 fd0 (driver?)
0300    4194302 hda driver: ide-cdrom
0340    4194302 hdb driver: ide-cdrom
No filesystem could mount root, tried: reiserfs ext3 ext2 msdos vfat iso9660
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(2,0)."

I have found it impossible to elicit the significance of the text in either of 
these messages.


Starting the machine with the root floppy made in section 8.4 provides the 
following data;
"
root (hd0,6)
Filesystem type is ex2fs, partition type 0x83
setup (hd0)
Checking if "/boot/grub/stage1" exists  ... yes
Checking if "/boot/grub/stage2" exists  ... yes
Checking if "/boot/grub/e2fs_stage1_5" exists  ... yes
Running "embed /boot/grube2fs_stage1_5 (hd0)"  ... 15 sectors are embedded.
suceeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+15 p 
(hd0,6)/boot/grub/stage2 /boot/grub/menu.lst" ... succeded
Done.
"

I am at a loss.  The grub boot loader says the system is unworkable but 
the response from the floppy triggering an unloaded machine says that 
there is nothing wrong with the boot loader or the relevant file structures.

Are there any checks that I can carry out on the build to confirm that 
it is healthy?
Have I wrongly called the hard disc /dev/hda7 in menu.lst?  This is how the 
existing kernel -2.6.18-dcc-smp labels the devices.
Can anybody recommend any literature that will explain simply what has gone 
wrong please.
