Question How do you read an IRIX cd using EFS

I am trying to read an IRIX cd that is in the EFS format using NetBSD 5.0.1

I added support for the EFS file system in the kernel and checked to see that pseudo-device vnd was in the conf file as well. I then built the kernel and installed it.

I issued the command
Quote:
mount -t efs /dev/cd0a /cdrom
and it returned
Quote:
Superblock read failed
I thought this might be because the cd uses 512 byte blocks so I used dd to make an image of the disk. I then tried
Quote:
vnconfig vnd0 /temp/test.iso
which does not return an error. Then I did
Quote:
mount -t efs /dev/vnd0a /mnt
and it returned
Quote:
efs: invalid superblock: sb_magic invalid
Is there something I am missing, or is it impossible to read an IRIX cd in EFS format using NetBSD? If so, I finally have to switch to Linux.
