Sometime Today, Dilip M assembled some asciibets to say:
I have done several Redhat-7.x remote installations using NFS method.
I created "bootnet.img "
# dd if=/mnt/cdrom/images/bootnet.img of=/dev/fd0 bs=512
When i boot machine from this floppy the installation stops showing "The Second stage of install which you have selected does not match the boot disk your using..."
perhaps you are using bootnet for RH 7.3 while trying to install RH 8.0.
Just curious, why did you go for RH 8 when it is no longer supported?
