Why cannot boot off my doc 2000 ?

[cytang <cytang_cn@yahoo.com.cn>]

I have make a new kernel which can support doc . and I
have make a mini system on my doc like the following 
/doc/{bin,etc,sbin,lib,dev,proc,var,usr,mnt}, and
copied files I needed in respective directories

I mount the /dev/nftla1 on /doc .
my /doc/etc/lilo.conf is :

boot=/dev/nftla
install=/boot/boot.b-mtd
map=/boot/map-doc
disk=/dev/nftla
bios=0x80
prompt
delay = 50
timeout = 50
image = /boot/bzImage-doc
label = linuxondoc
root = /dev/nftla1
read-only

run:  lilo-mtd  -v -C /doc/etc/lilo.conf -r /doc

Writing boot sector.

It seemed ok .but above why not /doc/boot?

If i remove my harddisk , I still cannot boot from my
doc . just get  "boot failure " .
why ?  Is something I did wrong ?  or I miss something
?
