You can use a special boot disk to partition your harddisk with the DiskDrake tool. For my server installation I made myself such a bootdisk.
So you can set your own partitions for the server. I use it to make the / and /boot directories on the first HDD and the /home on the second HDD.
You can download it and look (compare with the original boot.img on the CD) at the "install.cfg" file.
http://www.s235.de/sme_disk/boot.imgHere you can set the language, keyboard and time zone you want to have for your server.
I tried to preconfigure it for you, because my boot disk was made for a german installation.
Sorry, but I haven't more time to explain it. Look at the bootimage and try to customize for your needs.
I hope it is someting like that what you want.
