Greetings
I have an elderly version of ultrix (4.2A) which knows nothing of disks of
mind boggling capacity such as the two gigabyte RF73.
Does anyone have a later version of Ultrix with the dimensions of this
disk specified in the /etc/disktab file?
(p.s. has anyone else noticed that Altavista seems to be lamed
deliberately or otherwise so that Linux or Netscape clients can no longer
search properly? I have noticed this for a couple of weeks...I go into
work and use Internet Extorter on NT and everything is fine.)
Thanks in advance

Hi Paul,
Most of the information in /etc/disktab is useless nowdays. The
number of cylinders, heads, etc can safely be left out without
any problems.
What you do need is to decide on a partition table for the drive.
I usually choose the largest drive listed, copy it to my new drive,
and tweak the partitions covering the end of the drive to cover
the additional cylinders of my new drive. IE partitions a,b are the
same, c and h? are enlarged.
As to AltaVista, Netscape seems to have a problem with the Java
AltaVista uses to get stuff from doubleclick.net. This basically
locks netscape up (even disables button clicks in OTHER windows)
until it draws the stupid ad. I use I.E. to search, and Netscape
to surf :)

Thanks for the information
I found another solution as well. The old DSNlink database gave me the
total number of sectors on the RF73 and identified a RZ73 disk with the
same characteristics. On an old alpha at work was a disktab entry for a
RZ73. I was able to munge the RZ73 information into a RF73 disktab.
I was only interested in the C partition so the others may or may not be
valid:
rf73|RF73|DEC RF73 Winchester:\
:ty=winchester:ns#71:nt#21:nc#2621:\
:pa#131072:ba#8192:fa#1024:\

As the RF73 is a DSSI disk the notion of "cylinders, sectors, etc" are not
as useful as they were on the old MFM, SMD, and ESDI drives. In particular
the controller simply returns the block you asked for and does its own
access sorting.
In NetBSD you can query the raw device to get the total sectors (I don't
know if you can do this in Ultrix or not). Anyway, if you do that then you
can factor that total number and make up some cylinder/heads/sectors numbers.
As for AltaVista I gave it up for Google.com, why? because google's search
page is advertisement free and it returns better hits than Altavista does.

Very true. However, have you noticed how insistent the NetBSD guys
are about assigning a whole cylinder (however artificial the concept
of a cylinder may be at this stage, especially after auto map-out
of defective sectors) to the boot block? Yes, their boot block
spills past the partition table, but to insist on skipping a whole
cylinder when assigning the "a" partition, aw, c'mon... I recently
installed a system in which following their advice would have meant
to forgo about 2MB of storage...

... and if you can use it w/o IE, that's a major plus. One of my pet peeves
is when some app that doesn't really have to do with html insists on
installing IE so that you can browse its "improved" help/docs
(In particular, Digital Visual Fortran). It took a long time, but
I actually managed once to modify all that registry crap so that
DVF's help works with netscape. Otherwise, I would not have used their
help system. Simply put.

I have to agree. Though Google returns a lot of unuseable information, it
has proved to be my best resource when searching the impossible. Google
is the God of search engines. I'd use it even if the did have as as do
most competitors.
Why don't they have ads? It mystifies me.

Jeff
