ibm eserver x225 - 7.0 installation when btx halted / endless loop

[underlig]

I'm trying to install 7.0 RELEASE on my server, it's an IBM eServer x225 (8647-5CG (http://www-304.ibm.com/systems/support/supportsite.wss/quickpath?quickpath=8647-5cg&Go.x=10&Go.y=18&brandind=5000008) if that matters).

The problem i'm experiencing is that when i boot on the cd (disc1 or bootonly doesn't matter), i get an endless loop of numbers.
Booting on floppy gives me int=0000000d err=00000000 efl=00010006 eip=000219b2
eax=000219ac ebx=00000000 ecx=c0000080 edx=000587d8

BTX halted
Apparently x225s are somewhat incompatible with the standard freebsd installation, someone suggested to use the 7.0 snapshot bootonly, 7.0-STABLE-200804-i386-bootonly.iso gives me this screen and then nothing happens

Server has a 32bit XEON cpu, 4 gigs of ram, two 76gb hotswap SCSI-disks in a RAID1 array using the builtin LSI-controller. It's currently running windows server 2003r2 without problems, i can also boot the ubuntu server install cd with no problems..

Does anyone have any idea on how i can manage to install freebsd on it?

I'm just shooting in the dark here... Try a 6.3 CD and then do a source upgrade to 7?

Tried booting/installing 6.3 through http://unetbootin.sourceforge.net/ but that didn't work either although i didn't get any explanation why..

Since i don't have an rw-disc all this experimenting is getting expensive

So i tried booting from an old 6.2 cd, and a clean 7.0, same problems.

The scsi-controller is a "LSI 1030 SCSI Controller", could the problem come from missing drivers? If so, how do i add them to the bootcd? ( i mean since it halts after detecting the cdrom and the floppy when using 7.0-STABLE-200804-i386-bootonly.iso )
