Re: RAID1 size issue with PDC20265

Hi Peter,

it is not exactly controller (add-in card) - it is integrated chipset of
ASUS A7V motherboard with patched _BIOS_ to being able to boot from RAID
and use it under other supported systems (Windows perhaps) and have
redundancy for system boot as well too. I am not using patched dmraid (I
just pointed on that post in case if my problem has same roots). 

And as I said, it is working for me fine, but I am loosing here 100G of
redundant disk space, which is a bit disappointing ;-).

Regards,
Alex
