    Ok, thanks for the explanation about the scheme dependencies. I guess adding 
    a comment like "/* this must come before msdos */" in the respective line of 
    fs/partition/check.c could cut down in the number of people asking you the 
    same question over and over again.. :-)

    Hm, what do you think of these additional checks:
    
    1. Check for overlap of partitions
    2. Check for number of recognized partitions (i.e. size != 0) > 0 
    3. Check for struct ptec_partition.unused1, unused2, unused5 == 0 (assuming 
    they default to zero)
    Anyway, thanks again for the info.
