Hi all,
Thanks to all who replied (esp Thomas Blinn, John Losey, Raul Sossa and Murtaza Talawala)
>From Tom (thomas.blinn@compaq.com) :
------
Either the device will be recognized by system software as a CDROM
device, or it won't.
Try the command "scu show edt" to see your SCSI equipment device
table.
There is no special support in V4.0F for DVD drives. You might find
some third-party software that will do something useful. We added
some support in the V5.x stream and by V5.1A it's fairly useful, but
we won't have full support (as far as I can tell) until a release
AFTER V5.1A (that is, V5.1B or thereabouts, and that's not out yet
and probably won't be out for several months).

Which resulted in

>From Tom again:
------
As root, cd into /dev and issue the command
./MAKEDEV rz19
which will create the appropriate device special files for a disk class
device on SCSI bus 2 at target 3 (19 = 8 * 2 + 3).
In V5.x, the device special files would have been created "automagically"
for you when the system saw the device; in V4.0x you need to create them
by hand. The assumption is that you will take the time to read the info
in the system management guide about adding new hardware and follow the
procedures, or that you already know the stuff well enough to not need to
read the book.

>From Raul (RSossa@datadec.co.cr) and John (JLosey@Solucient.com) on the kernel rebuild
------
Apply the following:
1. >>> boot -file "genvmunix"
2. # /sbin/bcheckrc
3. # doconfig (not with -c option)
4. replace your current kernel vmunix.
5. # shutdown -r now.
6. # see in the "uer -Rr 300 |more " if you can see the DVDROM unit
(rzXX).
7. # see in " /dev/" if you have the correspondins rzXX partitions already
created.
8. # Insert a cdrom and check if you can mount it
by "mount -r -t cdfs -o noversion,nodefperm /dev/rzXX /mnt
------
I haven't actually completed the kernel rebuild as the ES40 is offsite so
it'll have to wait until it
returns before I complete the last step (device detection and creation
worked perfectly; it even
attempted to mount - of course this failed as it didn't understand the
format).
