the steps summary
run syslinux -ma g: (whatever your USB: drive letter)
copy \isolinux contents to USB:\root directory
ie the vmlinuz, isolinux.cfg , initrd.gz files..etc..etc.. to root
rename isolinux.cfg to syslinux.cfg
copy knoppix.img on cd to USB:\knoppix\knoppix.img

on booting up with USB
got past the F1 boot: screen
syslinux.cfg passes on to vmlinuz fine
until ...
looking for cdrom in...\dev\hda...\dev\hdc...
cannot find knoppix filesystem
drooping out to a very limited shell

there it stops...

on searching many sites i found many people with a similar problem.
i am glad its a linux related problem coz you cant find much support for
vista on the net these days
not for free anyway...
find just the quick suggestion "take it into the shops for a fix"
damm crooks, albeit its microsoft turning these sites off for a profit
anyway back to my pain...

i tried including "nodma" into my isolinux.cfg as some sites suggested
that dint work ...on booting
boot shows it is turning off dma for .../dev/hda .../dev/sda
...which is my hard disk and cdrom
there it went into searching for the compressed image in the cdrom again
i tried copying the image to root USB:\ knoppix.img

find it but fails

my guess is there are no parameters for syslinux.cfg and kernel to look
for compressed image in G:\ (usb)

Once the kernel has loaded the initial ramdisk initrd.gz into memory
mounts it as the root filesystem
the script ./linuxrc runs searching for the compressed knoppix image on the cdrom
OK
i will have to get into the ./linuxrc script to make it search for the cdrom

DOES anybody know how to do that?

OK i will just boot off the cdrom and access the ./linuxrc script
HANG ON ...
but i cant get to ./linuxrc script on the usb
it is compressed as part of the kernel (correct me if i am wrong)
the only files i get to play with on the usb - syslinux.cfg (formely isolinux.cfg)

how do i modify ./linuxrc and put that back into the usb
Do you get what i mean
if anyone is reading out there dont bother reply coz if i cant fix it
i ditch it .. USB=> knoppix
If the fs of your usb flash is fat16 KNOPPIX is knoppix!!! So your linuxrc script must be adapted.
Linuxrc is in minirt.gz (gunzip minirt.gz; mount minirt /media_somewere; vim /media_somewhere/linuxrc;sync:umount /media_somewhere; gzip -9 minirt;cp minirt.gz in your thumbdrive.

Cheers
