syslinux and 2.4.0 initrd size problems
I am having trouble getting a 2.4 vmlinuz (bzImage) and initrd image onto a 1.44 floppy with all the new stuff. Even a stipped down kernel compiled under 2.4 is @ 600K compressed, and I need about 800K for the initrd image. I noticed that syslinux has some comments about not allowing initrd to span media.
I there something more current that does or will allow me to load the inittrd off a CD-ROM device (with vmlinuz and syslinux
on the floppy). I know how to do this with GRUB (Grand
Unified Boot Loader), but I want to use syslinux if possible.
Thanks
Jeff

Why are you posting this to the kernel list? See the SYSLINUX documentation for the SYSLINUX mailing list address.

Never mind. I am rewriting the install init program instead and restructuring the driver organization to do what I need.

Happily using initrd on a 1.44 floppy here, and there should be no reason why you can't use it for a CDROM distro as well, you can have syslinux on the CDROM too... I believe their is a a syslinux mailing list to check if you have problems, and he has recently released updated versions of syslinux.

I've got it working here too, but not with an initrd image and vmlinuz image that's bigger than the floppy.

Check out what Debian did for 2.2 ("potato"). Kernel and syslinux are on a FAT floppy, and a second floppy holds a raw ext2 image, gzipped. SYSLINUX.CFG begins like so:
DEFAULT linux
APPEND vga=normal noinitrd load_ramdisk=1 prompt_ramdisk=1 ramdisk_size=16384 root=/dev/fd0 disksize=1.44 TIMEOUT 0
DISPLAY debian.txt
PROMPT 1
Just before mounting the root filesystem, the kernel says "insert floppy and press <enter>" or some such.
You can download the images at
http://http.us.debian.org/debian/dists/potato/main/disks-i386/current/images-1.44/
See 'rescue.bin' (syslinux+kernel) and 'root.bin' (initrd.gz).

If you can count on having a BIOS that knows how to boot a CD-ROM (i.e. the BIOS is new enough to be Y2K compliant) you can put a 2.88MB floppy image on the CD for the BIOS to find. Should be big enough for the next year or two.
