FREEBSD_INSTALL failed with error 19 during booting installer

[Marek Salwerowicz]

Hi list,

I am trying to install FreeBSD 9.1-Release amd64 on a Supermicro server:

SuperStorage Server 6027R-E1R12N

with Intel Xeon E5-2640 CPU and 32 GB (4 x 8 ) KVR16R11D4/8HC installed

Currently I have only 2 SSD Kingston  drives (working in mirror) 
installed on that server.

during booting installer from the ISO CD (amd64),  the boot process 
fails with message:

Mounting from cd9660:/dev/iso9660/FREEBSD_INSTALL failed with error 19.

As I found here: http://forums.freebsd.org/showthread.php?t=36579 , 
probably this could be issue with ACPI, but setting option in loader:

# set debug.acpi.disabled ="hostres"
# boot

made nothing for me.



Any ideas?

Regards,
