That's what I did to create a standalone boot disk.

1. Take a good quality 3.5" HD floppy.

Some of them claim to be able to sustain 2Mb capacity

2. Check if you have /dev/fd0H1722

$ ls -al /dev/fd0H1722

brw-rw---- 1 root floppy 2, 60 Jan 22 22:45 /dev/fd0H1722

if you don't have it do

$ mknod /dev/fd0H1722 b 2 60

$ chown root.floppy /dev/fd0H1722

$ chmod ug+rw,o-rwx /dev/fd0H1722

3. Insert the floppy into floppy drive. Do

$ fdformat /dev/fd0H1722

4. Do

$ mkfs.minix /dev/fd0H1722 1722

5. Check if you have /fd0

If you don't then create it

$ mkdir /fd0

Then do

$ mount -t minix /dev/fd0H1722 /fd0

6. Do

$ cd /fd0

$ mkdir boot

$ mkdir bin

$ mkdir dev

$ mkdir etc

$ mkdir fd0

$ mkdir fd1

$ mkdir lib

$ mkdir mnt

$ ln -s etc tmp

$ ln -s etc usr

$ ln -s etc var

$ cd /fd0/etc

$ ln -s ../etc adm

$ ln -s ../etc c

$ ln -s ../etc lib

$ ln -s ../etc local

$ ln -s ../etc v

$ ln -s ../etc terminfo

7. Compile your favorite boot kernel

the smaller the better

Mine is 1.1.64 with only ftape support

and has a size 203748 bytes.

8. Copy (use cp command - it doesn't copy a holes in files !)

your kernel to /fd0/boot

$ cp /usr/src/linux/vmlinuz /fd0/boot

9. Copy map and boot.b files from /boot

(or wherever they are at your system)

to /fd0/boot

$ cp /boot/boot.b /fd0/boot

$ cp /boot/map /fd0/boot

my /fd0/boot directory looks like

$ ls -al /fd0/boot

total 209

drwxr-xr-x 2 root root 96 Jan 23 01:13 .

drwxr-xr-x 10 root root 224 Jan 23 01:07 ..

-rw------- 1 root root 3336 Dec 13 23:50 boot.b

-rw------- 1 root root 3072 Jan 23 01:13 map

-rw-r--r-- 1 root root 203748 Dec 13 23:49 vmlinuz

10. Copy your libc.so.4 to /fd0/lib

Again: use "cp" command.

$ cp /lib/libc.so.4.5.27 /fd0/lib/libc.so.4

(I used old libc 'cause it takes much

less space)

11. Copy ld.so to /fd0/lib

$ cp /lib/ld.so /fd0/lib

12. If you wanna ftape support, compile ftape.o module

for the kernel and copy it to /fd0/lib

13. So my /fd0/lib directory looks like this:

$ ls -al /fd0/lib

total 760

drwxr-xr-x 2 root root 80 Jan 23 01:11 .

drwxr-xr-x 10 root root 224 Jan 23 01:07 ..

-rws------ 1 root root 132060 Dec 14 00:04 ftape.o

-rwxr-xr-x 1 root root 17412 Dec 13 23:57 ld.so

-rwxr-xr-x 1 root root 619524 Jan 23 01:12 libc.so.4

14. Goto /fd0/dev/ and create all relevant devices there including

fd0H1722,fd0

You can use MAKEDEV-2.1 from sunsite to do that

15. Copy all the following files to your /fd0/etc directory

(as it looks on my boot disk):

$ ls -al /fd0/etc

total 19

drwxr-xr-x 2 root root 320 Jan 23 01:33 .

drwxr-xr-x 10 root root 224 Jan 23 01:07 ..

lrwxrwxrwx 1 root root 6 Jan 23 01:08 adm -> ../etc

lrwxrwxrwx 1 root root 6 Jan 23 01:08 c -> ../etc

lrwxrwxrwx 1 root root 7 Jan 23 01:08 con80x25 -> console

-rw-r--r-- 1 root root 1383 Dec 3 02:13 console

-rw-r--r-- 1 root root 139 Dec 9 02:37 inittab

-rw-r--r-- 1 root root 5 Dec 14 00:07 ld.so.conf

lrwxrwxrwx 1 root root 6 Jan 23 01:08 lib -> ../etc

-rw-r--r-- 1 root root 248 Jan 23 01:06 lilo.conf

lrwxrwxrwx 1 root root 6 Jan 23 01:08 local -> ../etc

-rw-r--r-- 1 root root 29 Jan 22 23:02 mtab

-rw-r--r-- 1 root root 677 Jan 23 01:34 termcap

lrwxrwxrwx 1 root root 6 Jan 23 01:08 terminfo -> ../etc

-rw-r--r-- 1 root root 0 Dec 8 23:34 utmp

lrwxrwxrwx 1 root root 6 Jan 23 01:08 v -> ../etc

-rw-r--r-- 1 root root 1253 Dec 3 02:16 vt100

16. Here how these files look like on my boot disk:

$ cat /fd0/etc/inittab

id:0:initdefault:

si::sysinit:/bin/ldconfig

ca::ctrlaltdel:/bin/shutdown -r -q now

pf::powerfail:/bin/shutdown -qfs now

1::respawn:/bin/sh

$ cat /fd0/etc/ld.so.conf

/lib

$ cat /fd0/etc/lilo.conf

boot = /dev/fd0H1722

compact

delay = 5

#message = ./etc/message

install = ./boot/boot.b

#disktab = ./etc/disktab

map = ./boot/map

verbose = 3

backup = ./dev/null

image = ./boot/vmlinuz

label = Linux

ramdisk = 1722

root = /dev/fd0H1722

vga = normal

$ cat /fd0/etc/mtab

/dev/fd0H1722 / minix rw 0 0

And the file termcap contains the entry

only for linux|console|con80x25|dumb terminal

Files console and vt100 were copied from /usr/lib/terminfo

17. Copy the following files to your /fd0/bin directory

I have /fd0/bin as:

$ ls -al /fd0/bin

total 1002

drwxr-xr-x 2 root root 480 Jan 23 01:35 .

drwxr-xr-x 10 root root 224 Jan 23 01:07 ..

-rwxr-xr-x 1 root root 67812 Jan 4 00:58 unzip

-rwxr-xr-x 1 root root 103428 Dec 14 00:21 vi

18. Now the main part. Do

$ cd /fd0

$ lilo -C ./etc/lilo.conf -r /fd0

19. Upon success of previous operation you should get

your boot disk ready. Finally do

$ cd /

$ umount /fd0

20. You are done. Reboot and enjoy your boot disk.

Works great for me.

Cordially,

Sergei
