Thanks for the documentation.

I managed to compile the kernel so that it supports Xenix FS. Unfortunately
it still does not work. The message is the standard saying something like
"either you selected an invalid device or the filesystem you are trying to
mount is garbled". It said something about a supposedly damaged
superblock.
Right now I am installing open Server 5.05 for the second time - the first
time I installed to a SCSI-Disk and was unable to add support for IDE after,
it ssems IDE Support cannot be added to an up-and-running SCSI Sytem even
though it works vice versa.

Hope, I will be there soon. Hopefully not only to discover that the
filesystem is damaged an cannot be read no matter what....

Keep fingers crossed!
