Anyway it boots fine but then the video mode is at a frequency such that no text is clear and it is moving around on the screen a bit (like running X i modes a machine cant handle) So I think, all I need to do is type the command line in somewhere to set it to a vidmode I know works on the machine. However this alas does not seem to work, there is some data that flashes up in 80x25 before the vidmode switch on booting any kernel wether it be off floppy or through bootx into the current ydl install. And looking in arch/ppc/boot/misc.c this seems to be useful and interesting information including a bit that should wait for 5 seconds for me to enter command line arguments. Howevedr the information flashes past so fast I cant even read it. I am then on booting off the debian install floppy put into this unusable video mode. I tried changing the #defined CMDLINE in misc.c to have the appropriate vidmode command, but then I noticed on a simple makevmlinux the make process didnt even enter the boot directory and compile the changed misc.c (all this is using a 2.2.18pre18 from paul's ppc.samba.org from yesterday) What I want to know is what is the official (tm) way in which I am supposed to put a command line that will actually be used into the kernel for booting off the debian hfs rescue floppy. I made the image I wanted fine and gzipped the vmlinux and placed it on the floppy but due to there being no setting of video mode it still boots into an unreadable text frame buffer. I assume rdev is specific to i386 and compressed images. I notice the floppy uses a simple gzipped vmlinux, not a compressed ppc zImage even. I assume it may help me to know for future reference how to set the kernel command line if I am no longer using bootx and thus wil be unable to just leave the command line there.
