Problems installing 5.2.1 release on AlphaServer800

[Mogamat Abrahams]

Hello,

I hope someone can help me, I have tried searching the mailing list 
archives at http://freebsd.rambler.ru and found some references to my 
problem but nothing conclusive.
I have a AlphaServer800 with 2x 9.1 gb scsi disks, when I try to install 
FreeBSD/alpha 5.2.1 release from cd, I cannot create any partitions, and 
I am not even presented with the Fdisk screen as on i386. If I try any 
of the options in the Disklabel i sometimes get a sigev11 and have to 
reboot.
Any help would be appreciated.

Mogamat
