My default file looks like below with no line breaks:
prompt 1
default linux
timeout 100
label linux
kernel vmlinuz
append ksdevice=eth0 load_ramdisk=1 initrd=initrd.fc7.img network
ks=nfs:10.254.13.1:/home/tftpboot/kickstart/10.254.13.112-kickstart
ramdisk_size=9216
When I get to the boot line, I type "linux". The vmlinuz and
initrd.fc7.img are loaded. Then a "Ready" message appears. Then the
system boots with Fedora Core 7. Is there any way I could try your
fc7-install.img? I still wonder if that is where my problem lies.
Thanks,
Gary
