since, the boot fails, I cannot get there
>Description:
FreeBSD 5.5 and before do not exhibit the problem since they use BTX 1.01.  If I try to boot the system on FreeBSD 6.4 which uses BTX 1.02 and an array is defined in the serveraid adapter (tried Serveraid 3L, 4L, 4Lx, etc.) the boot freezes when trying to assign bios drive C right after Bios A drive is assigned.  It does not halt or provide any information, it just freezes.  If the serveraid adapter has no array defined, drive c is not assigned and booting works but installation fails since no drive is present to install.  Same behaviour whether cd or disks are used to boot.  I tried on on IBM x326m, IBM x300 and IBM x306m with same results.
>How-To-Repeat:
Configure a raid-1 array on a scsi based serveraid adapter 3L, 4L, 4Lx and try to boot FreeBSD with a BTX 1.02 (6.4-Release or more) and the freeze should occur.
