Yes. PXE + dhcp + pxegrub + tftp + installation image and initrd.

Rebuilt grub to enable network support and to stuff in a default menu 
that makes it let you use grub over the serial terminal.

If you must use the CD, then you need to pass something like 
'console=ttyS0,9600' to the kernel.

After installation, anaconda should create appropriate grub menu 
entries. If not, look at the sample below.

serial --unit=0 --speed=9600
terminal --timeout=2 serial console

However, what do you mean by 'installing grub on to both disks, you have 
to get a shell window during the install'?

Are you trying to get around the first disk fails and the system does 
not boot up any more problem? That is fixed on Centos 5/RHEL 5.
