booting with gdth disc array controller

[Rainer Sigl <sigl@mpe.mpg.de>]

Hi,
I have a internal Raidcontroller gdt6523RS and it works fine with
debian 2.4.9 and the gdth driver.
The only Problem is booting. I would like to boot from bei root-disc
/dev/sda from my raid but I can only boot from floppy.

I guess the driver for accessing the raid has to be known at boottime.
Is it necessary to load gdth in some construction of ramdisk?

Has somebody experience with this device? How to build a image for
the ramdisc?
