[CentOS] HW issue during instalaltion

Hi All,

I have a shuttle SN78SH7 with a Seagate ST31500341AS (1.5Tb) drive. With 
windows Vista it sees the drive and can install to it.  So far with GRML 
or CentOS5.2 they do not seem to be able to see this drive.  Is there a 
particular setting I need or does CentOS not support installation to 
these drives yet ?

Thanks for your help

Phil
