[ros-dev] FreeLdr: FsOpenVolume

[Filip Navara]

Hi,

since there have been several reports of the ROS CDs failing to boot 
with the "Invalid partition table magic" message I though if the line 85 
in freeldr/fs/fs.c can be the cause. If the CD-ROM drive would get 
assigned the 0x80 BIOS number (can this everr happen?) then we would end 
up reading partition table from it and crash later.
Any thoughts?

Regards,
Filip
