Description of problem:
After installing Red Hat 7.0 via CD-ROM on an i386 system with two hard 
drives (430 MB & 3500 MB), I reboot and get the following error:

EXT2-fs: 03:01: couldn't mount because of unsupported optional features.
[MS-DOS FS Rel. 12, FAT 16, check=n, conv=b, uid=0, gid=0, umask=022, bmap]
[me=0xa, cs=40, #f=0, fs=900, fl=19978, ds=900, se=30976, ts=-1702297342, 
ls=5376, rc=0, fc=4294967295]
Transaction block size=512

Neither drive contains MS-DOS or Windows, and both were formatted 
completely during the install.  No special options were selected.

How reproducible:
Always

Steps to Reproduce:
1.Install Red Hat 7.0 via CD-ROM
2.Reboot system
3.
	

Actual Results:  The results are given in the description above.  This 
problem may be unique to my system, although some time ago, Red Hat 6.0 was 
running on it.

Expected Results:  Normal boot up

Can you tell me which kernel is running?  That will be the first thing announced
at boot time.  One possibility here is that you have actually picked up the
kernel from the old 6.0 install: that can happen, for example, if you previously
installed the "lilo" boot loader onto /dev/hda but picked /dev/hda1 for the new
install of 7.0.  In that case, the /dev/hda copy would have priority and you
might accidentally end up running an old kernel on the new distribution.
