Question a query regarding the installation of linux in ibm z/800


Hi all,
I have a ibm z/800 machine that has to be installed with linux.I have suse 7 which is ment for s/390.The doubt i have is that s/390 is an 31bit PU whereas the z/800 is an 64+ bit PU.Can anyone help me with this.
If the answer is yes the i want to know why i should run a OS which is 32 bit and ment for 31 bit PU on an 64 bit environment.
If the answer is no can i have some reasons for the same.I have a doubt for the drivers support too.

Whoa !!!!
Didn't expect to see z/Architecture queries here.
And while I appreciate you probably had a problem trying to work out where to post this, AIX is *NOT* Linux/390 !!!!.

*ALL* S/390 code will run on z hardware. O.K., slight exageration, but close enough for this discussion.
The 64-bit extensions are *VERY* recent, and you should not concern yourself *AT ALL*. The hardware will handle both without you ever being aware.

I'd suggest you cruise on over to http://www-1.ibm.com/linux/ and aquaint yourself from there.
More info than you could ever want I suspect.

Believe me. this will be the least of your concerns with this hardware.
If some-one has provided you with an environment (basic mode, VM, or LPAR), and asked you to install Linux, go ahead and do so.
If you have to establish the hardware environment, I suspect you are well out of your depth.

Tough situation.
The hardware is proprietry, and there is no competition.
If you have a maintenence contract with IBM you might be able to get them to give you access to a website called Resourcelink.
If you got the box from a broker, I suspect you are out of luck.
The manuals on that site presume you have a) an engineer to do the install, and b) some experience in the field to do the customisation.

We have bought the box from ibm.As you have suggested i have asked them to give me the resource link,whic i think would be enabled today.Thanks for the advice buddy.
I have found the manuals as well.I found some more information which proved too useful.Yesterday i installed suse and redhat using z/VM by just going through the manuals.Linux is just looking gorgeous in a mainframe.

Glad to hear it.
I was concerned that you didn't have a cconfigured machine - particularly the I/O Definition File. This would have inhibited machine start-up.
But with z/VM active, you'll have *lots* of fun.

Not so sure about concepts, but www.mainframelinks.com might be a start.
Checked a couple out, and they looked o.k.
I found it with google - spend some time searching, you'll find heaps.
