That part is wrong: both the '|' and the '<<' signify content for stdin.
Change to:
fdisk /dev/cciss/c0d0 << EOF

You can also combine both fdisks into one.

I use this highly-redundant script in another context:
[root magpie root]# cat /tftpboot/installer/bin/dl/dl-partition
#!/bin/bash
export BootPartition=25 RootPartition=''
function partition_disks()
{
#fdisk -l /dev/hda
dd if=/dev/zero count=1 of=/dev/hda
fdisk /dev/hda <<E
d
1
d
2
d
3
d
4
n
p
1
1
+${BootPartition}M
n
p
2

${RootPartition}
p
w
E

}
[root magpie root]#

The dd is there because I wanted to clobber the MBR.


As to the specific error you have, we need better information.

If you are using a text install, you can get this by using a null-modem
cable and minicom. Configure minicom to not initialise the modem, set a
speed of (say) 57600.

Boot the install kernel:
linux console=ttyS0,57600

If you're doing a graphical install, on your workstation
xhost +
echo $DISPLAY
and boot Linux
linux DISPLAY=myworkstation:0

Change ':0' to suite: I might use '12.0'
root kite:~# echo $DISPLAY
localhost:12.0
