Subject: Reading the BSD partition table from Linux/Intel

    Hi,

    UP2000 has an on-board Adaptec AIC7896. Recently, the motherboard
    itself got screwed. I now need to access the data in the hard disk
    attached to that system. The hard disk has the BSD disklabel, and
    I need to access the partitions. So.....

    I made a custom-built kernel to support such a partition table as the
    BSD disklabel. I booted the machine with a Symbios controller from
    an normal hard disk without the BSD disklabel. I then tried to
    open the partition table of the hard with the BSD disklabel with "fdisk".
    It failed with an error message: The partition table is not
    readable. I did not get a prompt for typing in "b".
     
    I don't have an Adaptec controller to be used in an Intel machine,
    because the UP2000 has that as an on-board controller.

    May I ask this? During kernel compilation, there are two locations
    related to BSD_Disklabel. One is UFS filesystem Support and the other
    is BSD Disklabel Support. I selected the latter only because the
    file system type must still be ext2. Isn't it? The partition table
    is only the BSD_Disklabel. Should I choose both?

    I know about "dd". But I need to know quite a lot on how to use "dd".
    Maybe, I can find the information regarding dd. But after that,
    I know I should not do anything funny. That option is not available to me.

    Next time, I would use a small SCSI hard disk on UP2000 or on
    any other Alpha/Linux with the SRM console with only the /boot
    partition. All other hard disks attached to the system should
    have the DOS disklabel, not the BSD disklabel.

    Could anyone help me access the data?

    Thank you very much
