- COH's ADAPTEC DRIVER IS DEFINITELY DAMAGED. Those MWC guys didn't
- perform controller initialzation in the driver but relied on
- defaults from the controllers firmware. These defaults are
- ABSOLUTELY INSUFFICIENT for any multi-user/-tasking operating system
- as stated in many documents (XENIX, SCO, INTERACTIVE UNIX etc.).
- From the docs you can read clearly that BUS-on times greater than
- 8 ys will definitely lead into floppy-I/O ill-behavior. This can go
- that far, that the floppy drives' heads banged against the spindle, since
- the floppy driver forgets about all its administration data (head,
- track and sector mapping), what I could observe when I was restoring
- multi-volume archives with the uninitialized AHA-1542B.
-

- Congratulations MWC-Guys -- your neatly OS can even destroy hardware!
- What a progress on the OS market!
- ---
-
- I wrote a tool called 'ahaset' that fixes the missing controller
- initialzation at run-time, since the current kernel still permits
- direct writes to hardware ports. Everybody who operates an
- AHA-1542B too, should request this tool -courtesy of CUC-Ger- with
- a short mail.
-
- Now the bad news ...
- Setting Busmaster-DMA timing (BUSon/BUSoff) to decent values does not
- cure the problem with severe character loss on tty lines. I.e that
- each disk access clobbers tty-I/O severely even if one sets
- Busmaster-Timing to 'worst case' for the SCSI-Bus (i.e Bus-On=2ys,
- Bus-Off=64ys).
-
- From 'bad' to 'worse' ...
- Using 16550AFN chips on serial lines does NOT cure the character
- loss problem but makes it even worse, since whole FiFo buffers of
- the 16550AFN chip trashed in this case (can be observed from the
- error counts in 'uulog' files, which are increasing to values
- about 4 times as high) and thus UUCP connection will crash soon
- if you try using FiFo buffered SIO chips - impossible to work
- with, though.

- From your configuration it look, that you want the basic COH'
- system in an IDE environment. I'd recommend that you first try to
- install COH' on a minimum hardware basis (just floppy and drive #0)
- and then look if the problem shows-up again. Leave out the virtual
- consoles too in such a minimum configuration.

- Start with reading the man page 'doscp' and follow the "See Also"
- entries - that's the way to dig through UNIX docs, anyway ...
