Highpoint 372 Gentoo installation on existing RAID array

[BE13]

Problem: installing Gentoo on a multi-partitioned Highpoint 372 (HPT372) RAID 0 array.

I am trying to install Gentoo using the Universal LiveCD.

Highpoint 372 controller using an existing 80GB RAID 0 array (2 x 40GB drives):
- partition 1: 20GB, NTFS Windows Installation
- partition 2: 20GB, FAT32 Windows installation
- partition 3: 20GB, FAT32 Windows Installation
- partition 4: 20GB, NTFS Free

I would like to use the partition 4 space to install Gentoo on. I assume that can be arranged during the installation process.

Once the Gentoo installation procedure starts, I arrive at the prompt. I am able to manually configure the network settings so I can access the internet. Also, I am able to mount the floppy drive on which I have the Linux source code for the Highpoint 372 controller (actually, all files contained in this compressed file: link).

fdisk /dev/hda doesn't work since /dev/hda doesn't seem to exist. Using the mount command, I see my floppy and the CD-ROM are mounted and accesible, but not the RAID array. From what I read, I have to compile the kernel using the source code for the Highpoint 372 controller. Highpoint provides some instructions:

make KERNELDIR=/usr/src/linux-2.4.7-10

Whenever I try to use that code, I am told the command "make" is not known. Also, I am not able to find "linux-2.4.7-10" in the /usr/src location on the Gentoo Universal LiveCD. There is a file called "Makefile" on the floppy, but I am not sure how to use it.

Also, I would like to know if by compiling the kernel myself using the source for the controller I can avoid having to use an older kernel, as reported in some other threads.

No luck yet ...

Is it at all possible to compile a driver from within the installation of Gentoo? I know the Gentoo Universal LiveCD has kernel 2.6.7, so I should be able to use that to compile the Highpoint driver. The problem is, in one of the Highpoint files it says:

#include <linux/sched.h>
#include <linux/blk.h>
#include <linux/errno.h>
#include <linux/string.h>
#include <linux/pci.h>
#include <linux/wait.h>
#include <linux/ioport.h>
#include <linux/delay.h>
#include <linux/proc_fs.h>
#include <linux/interrupt.h>
#include <linux/init.h>
#include <linux/kernel.h>
#include <linux/smp_lock.h>

which is referring to files I cannot find on the LiveCD. Do I have to install the kernel to be able to access the files on the above locations? If so, can this be done by compiling from within a Knoppix session? (Knoppix works since it doesn't install anything, and therefore does not need my harddrive setup)
