I am in the process of making a new 2 -3 floppy distro..to be loaded
into....RAMDISK .....I used the BootDisk howto to get me going and I got
the boot disk set up fine but I am having trouble with the root disk...when
I got the rootfs all set up I used dd if=rootfs bs=1k | gzip -v9 >
rootfs.gz and then used dd if=rootfs.gz of=/dev/fd0 bs=1k and got it
transfered to a floppy...I boot with the boot floppy ok but during bootup
when I insert the root floppy...after it says insert root floppy to be
loaded into ramdisk and press ENTER I insert the floppy and then press
enter...it then says RAMDISK compressed image found at block 0...which its
supposed to...but then I get a error.....invalid compression format
<err=2><5>...what is the problem I have tried 5 different floppies
including 1 new...I would really appreciate it if somwone could help
me....I have tried 4 or five different ways of compressing it and using the
dd command to transfer the root.gz file to disk...
Here is what I have tried...

dd if=rootfs bs=1k | gzip -v9 > rootfs.gz 
then dd if=rootfs.gz of=/dev/fd0 bs=1k 

dd if=rootfs bs=1k | gzip -9 > rootfs.gz 
then dd if=rootfs.gz of=/dev/fd0 bs=1k 

gzip -c -9 rootfs > rootfs.gz 
then dd if=rootfs.gz of=/dev/fd0 bs=1k 

dd if=rootfs bs=1k | gzip -v9 > rootfs.gz 
then dd if=rootfs.gz of=/dev/fd0

I even tried rawrite under dos...it still didn't work....
 
                                          plz if someone could help me

   Thanx,

Can you boot it using loadlin?

C:\ loadlin kernel initrd=rootfs.gz root=/dev/ram0 rw

Format the floppy.

fdformat /dev/fd0H1440
dd if=rootfs.gz of=/dev/fd0H1440
