Kivckstart vis USB cdrom

[Gerald Waugh]

Hi,

First post;
We are installing CentOS4 via a USB cdrom, and have a problem.
The server boots just fine from the USB cdrom.
At the boot prompt we enter "linux ks=cdrom".
If we do nothing else, the install drops into 'text mode'

If we pull the USB cable and reinsert when the console reports 
"running /sbin/loader" the kickstart script is run and everything is
fine.

Any ideas as to how to fix this, much appreciated.

TIA
Gerald
