Running Linux/390 on the P/390
This is actually easier than it looks.
Here are the things you need to know to install SuSE GA 7 from the ISO
Copy initrd, awsoma.tdf, parmfile, and
tapeipl.ikr to some directory you define as an OMA 3420 tape in the
P/390 Configurator (AWSOMA is manager K on my setup--your mileage may vary).
I made my tape device address 581.
Add a 3215 console to the P/390; I put mine at address 0009.
If you've got an Ethernet or Token-ring interface on your P/390, add it; I
called mine a 3172 (manager A for me) and put it at 0400-0401. Linux
uses this with its lcs driver.
Edit the awsoma.tdf file to point to the correct paths where you put
the three files that belong on the boot tape.
Edit your parmfile to include mem=124M condev=0009. For whatever
reason, the P/390 doesn't want to let you use that last 4M of memory. If
you're installing on a 32M system, I can't help you--SuSE requires a 32M
ramdisk to work. You might be able to make Marist work in 32M, but I've never
Create a couple of disk images; I used an 800-cylinder 3390 at 0120 and a
20-cylinder 3390 for swap at 0121. You probably want more space or more
IPL 581. This should bring up SuSE on the 3215 console; answer
the networking prompts, then telnet in and run YaST as usual. You can either
mount the CD-images on an NFS-accessible drive, or just mount them as FBA
images (3370 works well, and mount them as /dev/dasdX, not /dev/dasdX1)
that the L/390 box can use.
That's it; you're done!
