: Venix does an fsck upon boot.  This may be why your HD head is seeking?

This 2 minute head banging bit is prior to any venix msgs (right
after digital logo).  I have had a chance to try another st-225 and 
the st-4038 and they also exhibit the same problem... so it is probably
the software.  The 30mg drive did not work btw (disk read msgs during install)
maybe the heads/cylinders of the st-4038 are not the same as the RD-52.

Everything is setup correctly for remote logins.  In fact, remote 9600 
baud logins are so convenient, I even put away the monitor and keyboard 
in my closet.  Venix is nice.  P/OS is junk.  Sure, it doesnt  quite 
compare to SVR4 or BSD4, but its still totally cool.  I'm impressed.
Thanks!

I wrote several small test programs and utils to give the c compiler a spin.
Disk seeks really slow it down, but otherwise its acceptable.  I am 
planning on getting the following compiled: rz, sz, uue/uudecode,
compress/uncompress, unzip... + some other interesting tools.
If someone has already done any of the above, kindly let me know.

Also ran an old dhrystone benchmark program (avail from wuarchives.wustl.edu 
as /unix-c/benchmarks/dhrystone.c)

If someone has an ftp site we can use, I will teledisk some of the Pro stuff.
