Ultimate Boot CD

sorry for my poor english, i'm french guy.

i have a problem. I install uBCD v 4 on my usb drive and it works fine, but
it's impossible for me to lauch my Pro1.dat boot for windows xp installation.

LABEL XP Pro install
MENU LABEL XP Pro install
KERNEL /PRO1.DAT
APPEND

error: not kernel boot available


I have changed it by w2ksect.bin and it's the same.

LABEL XP Pro install
MENU LABEL XP Pro install
KERNEL /w2ksect.bin
APPEND

error: Memory overflow error


in others version this code works to lauch installation of xp (cd).

if ($lastKey == key[f9]); then chain /PRO1.DAT


Please, help me. thx very much.

nobody ?
