I am not a Linux OR PC expert but...
A whole bunch of things might be involved in these problems.
With respect to the HD;  The BIOS mode of accessing the HD can be
changed and linux will deal with it but DOS will not.

It is not all that hard to have incompatible "pieces" when
"re-installing" with lilo being one of those pieces that is real easy to
forget about.

It is even possible to "upgrade" and end up with lilo booting the old
kernel (not necessarily easy mind you but it CAN be done -- probably
easier accidently than on purpose).

As to the cdrom; Once the installation is complete you must have the
correct entry in /etc/fstab AND for most instaltions, explicitely mount
the cdrom (I don't know how familiar you are with Linux/Unix).

DOS is REAL picky which is why most experts recommend setting up the DOS
partion with DOS FDISK.  Once DOS is running and understands it's own
partions then you install Linux (although it is really lilo that has to
be installed after DOS is set up).



1. Please Help! Slackware Boot Disk CRC Error

: I have InfoMagic's Aug 95 Linux CD set, and am trying to install
: Slackware.  I have a Mitsumi CD-ROM, so am using the Mitsumi
: boot disk image.  When I try to boot with the disk (which I have
: recreated several times without errors), it runs for awhile and then
: gives me the following message:

: boot:
: Loading ramdisk......
: Uncompressing Linux... large kernel, low 1M tight...

: crc error

:   -- System halted

: Does anyone have ideas as to why I am getting this message and what
: I can do to get rid of it?  Any comments are appreciated.

reformat the floppy drive ON THE MACHINE that will read it afterwards. Then copy the contents on it again.
That usually fixes it for me.
