I am also operating on existing miboot floppy, so I can do it the way Rogerio did. > > > > To create a working miboot floppy that boot a root on HD (no initrd) I > > > > assume I must also use the perl script patch-floppy-image.pl to set > > > > the "root=" argument to whatever partition the rootfs exists on, > > > > right? > > > > > > Just add the right root= to KERNEL_CMDL. The boot arguments can be set with the "patch-floppy-image.pl" script. Setting the root device at compile time is rather static, don't you think? (Nothing bad with a default root device compile time setting though, but for anything but an initrd that is too static to be useful). > > Thanks for the info, I will probably not have time to try it out until > > the weekend though. > > No problem. OK, for the first time ever I have succeeded in getting a self-compiled kernel to boot with miboot and produce output :-) Though I almost gave up too early, the first floppy I tried was bad, but I thought it was the kernel (or miboot, or a combination). Luckily I tried another floppy and there was output. I modularized a bit too much though, so the kernel didn't do the partition check and never found the partition to mount / on. But that is solvable, compiling again as I write this. This time I even include a driver for the nic and support for / on NFS. If that kernel fits the floppy, that would be really cool IMHO. -- Hans Ekbrand (http://sociologi.cjb.net) <[EMAIL PROTECTED]> GnuPG key: 1024D/7050614E Fingerprint: 1408 C8D5 1E7D 4C9C C27E 014F 7C2C 872A 7050 614E Learn about secure email at http://www.gnupg.org
