This would be the debian etch netinstall iso or business card iso. Doing this only "fakes" a cdrom device. I do not recommend booting from the same device and using a separate partition on that same device as the partition containing the debian netinstall or business card iso as the ramdisk boot installer. It might work since ybin or yaboot or quik are not installed. Not sure of command sequence for miboot boot loader but I would guess it would have problems . I have tried this "fake" cdrom on a Alpha with etch and it works. If you have a netinstall that you can boot than you are set you can just dd that to the boot disk drive and install to the other one. But if the image will not boot you might have problems. Use "dd if=/dev/zero of=/dev/hdb" to zero data on the disc if you experience problems with the disc you wrote to. >>> part.

Several archs, ports or whatever you want to call different computers allow TFTP from the BIOS. Such as my SGI Indy and my Alpha PWS have TFTP clients built into the ROM . When you get into closed firmware such as on the your PB1400 or my 3 nubus (really it is PDS) powermacs TFTP would need to be started after a kernel has already loaded thus defeating the purpose. Perhaps what you are really looking for is a ram disk install image with network capabilities built in, basically a netinstall you can boot. Booting being the plus.
Florian do you know Simon Horman ? He was the Debian builder for the nubus-images if he is still at debian he might be the one to contact to get it back in debian. Or Sven Luther. http://lists.debian.org/debian-powerpc/2005/11/msg00336.html Cheers, Rod Ross ---AV & Spam Filtering by M+Guardian - Risk Free Email (TM)--- ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
