is it possible to put gentoo in a foppy with:
->cdrom support with all old proprietary busses
->a console
->vfat and ide support
->pc-card (optional)
->usb 2.0 pc-card support(optional) |

Perhaps it's possible to put a kernel based on the Gentoo patchset on a floppy, but not the distribution and not even a minimal part of it.

Gentoo is not geared towards floppies.

The info pages on GRUB have a section "3.1 Creating a GRUB boot floppy" | Code: | On a UNIX-like operating system, that is done with the following
commands:
# cd /usr/lib/grub/i386-pc
# dd if=stage1 of=/dev/fd0 bs=512 count=1
1+0 records in
1+0 records out
# dd if=stage2 of=/dev/fd0 bs=512 seek=1
153+1 records in
153+1 records out

There's "grub-install" but there are warnings about its use | Quote: | | *Caution:* This procedure is definitely less safe, because there are several ways in which your computer can become unbootable. For example, most operating systems don't tell GRUB how to map BIOS drives to OS devices correctly--GRUB merely "guesses" the mapping. This will succeed in most cases, but not always. Therefore, GRUB provides you with a map file called the "device map", which you must fix if it is wrong. |

i made it with ubuntu and a blank floppy(easyer)
now i have a problem with my external hdd that isn't reconised
what do i need in order to have my external hdd
i think that usb is ok scsi may be the problem
roughly
grub on a floppy->change the floppy for the floppy with the kernel->boot the kernel that will boot on the gentoo that is on an external hdd
(it's for installing linux on a very old computer) |

| Code: | # ROOT="/home/embedded" USE="make-symlinks minimal -nls" emerge -av uclibc busybox
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-libs/uclibc-0.9.28 to /home/embedded/ USE="minimal -build -debug -hardened -iconv -ipv6 -nls -pregen -savedconfig -uclibc-compat -userlocales -wordexp" 0 kB
[ebuild R ] sys-apps/busybox-1.2.1 to /home/embedded/ USE="make-symlinks -debug -netboot -savedconfig -static" 0 kB
Total size of downloads: 0 kB
Would you like to merge these packages? [Yes/No] |
this is 5.5 MB uncompressed
compressed this does 1.4MB in tar.bz2 and 1.5MB in squashfs
how do i put this on a 1.35MB floppy?
is there a way to decrase the space used by uclibc and busybox? |

Try removing any and all non-essential files. Look around $ROOT/usr/share (especially $ROOT/usr/share/doc). Also make sure to compile them with -Os instead of -O2 and potentially drop even -fomit-frame-pointer since it causes very small size increases too sometimes.
However, I *did* warn you that Gentoo is not suitable for such tasks.

what is the saveconfig option on busybox?
i have compiled it staticaly(that mean without the dependency of glibc) and i have now:
1.8 MB staticaly
872 k in squashfs
L:ess than in tar.bz2 that is 1.3MB
how do i boot on a loop file that is in squashfs?
do i dd if= of= the floppy? |

If you need a small shell, try app-shells/ash.

I apologize, brain fart on my end. What I meant was app-shells/sash.

D'oh...
You should also create the null and zero devices, as well as perhaps random and urandom, via | Code: | mknod /dev/null c 1 3
mknod /dev/zero c 1 5
mknod /dev/random c 1 8
mknod /dev/urandom c 1 9 |

There's an even easier way:
| Code: | # grub
grub> root (fd0)
grub> setup (fd0)
grub> quit |
Or alternatively, I have an EXT2 floppy image with Grub loaded here: http://dev.gentoo.org/~redhatter/misc/grub-0.96-r2.img.gz

| Is that occurring after booting from the floppy? "No such file or directory" can be the result of missing shared libraries. |
