Thanx Sun Admins,
to all who replied. You are better and faster than the best commercial
support. I got answers from (in sequence of receipt):

The "winner tip" was from David Kelly. He suggested to toggle the PROM
variable "ttya-ignore-cd" to "true".

Most people (4) suggested to move to Solaris 2.6 (03/98) because of PCI
support. In my orig request I forgot to tell that Sun delivered the machine
with a preinstalled 2.5.1, and it worked.
But I think this advice is a good one because you don't have to install
additional patches and drivers.

One guy assumed a harddisk or SCSI fault, and suggested to replace
the disk. I was able to exclude this as reason for failure.

Thanks again to all, Guenter

--- Original question ---------------------------------------------------------
Last week I got an E450 (512MB, 1 250MHz-Proc, 2 Disks with 4.5 and 9.1 GB).
My console device is an old DEC VT220 Terminal (RS232, XON/XOFF, 9600 Baud,
8N1). NVRAM variable input-device/output-device I set to "ttya".
Now I'm trying to install Solaris 2.6. First attempt was with US version
(08/97), second with European edition (09/97) but without success. Both
editions I also tried to install via network.

After Power On I got the "ok" prompt, and typed "boot cdrom".
Console Messages:

At the point with the with the "/" I got the hangup. Synchronously, the
fan soundness rapidly reduces (I don't know whether both events have a

Has anybody an idea what's the reason of this situation and (more important)
can anybody suggest a solution for installing Sol2.6 on that machine?
