Hi everybody.
I have an old IBM RS6000 Model 7025 F80 with AIX 4.3.3 installed with 2 primary scsi disks. I want to install linux (any flavor) on it. I downloaded and burned an iso image of debian (http://cdimage.debian.org/debian-cd/4.0_r4a/powerpc/iso-cd/debian-40r4a-powerpc-netinst.iso\), modified the first boot device config, booted from this cd and after some hours I hade a brand new perfect multi cpu 64 bit version of debian with linux 2.6.<something> :). after booting the machine says it has no installed os on it. i tried installing on both disks and same thing: perfect installation, but no boot 
. I also tried different partition schemes. the last partition scheme i used wasone partition per fs and vlm enabled. I also upgraded the bios firmware to the last version from http://www14.software.ibm.com/webapp/set2/firmware/gjsn and same results: perfect installation and no boot.
any help really appreciated 
Did you enter your boot device into the bootlist in the firmware?
You might want to read this:

You might have to click you way down ("RS/6000 systems", "F80") to get to your documentation.
I hope this helps.

Thanks for your quick answer, bakunin.
Yes. I modified the firmware and set the primary boot device at the disk I installed debian with no success. By the way, I followed your link, but it seems to be broken. I could arrive at the "cached" versions google has, but the final document is unavailable. can you follow it? if you can access the documents, can you attach them somewhere?
Thanks again
hi everybody. due to the described problems, i decided to come back and installed aix 4.3.3. a friend told me to install suse, and googling around suse issues, i found an IBM paper that describes the same issue I am having. These guys said they had to modify debian's partition scheme and solved this problem. the article's title is "Alternative Linux distributions for POWER processor-based systems. A review of unsupported Linux distributions running on POWER5". The link is http://download.boulder.ibm.com/ibmdl/pub/software/dw/linux/l-pow-linuxdistros.pdf
I will tell all of you soon what happened. in case of broken, links I have a copy of it
thanks to everybody
