regarding flash ROM

[sivakumar]

Before asking this question , I have gone through some of the old mails
in this group. I am bit confused after that ;-(


OK the question is as follow:

I have 256 KB flash ROM. I have built the linuxbios image
(linuxbios.strip file) and burned the image on the ROM at
0x30000 to 0x40000 (Image size 64 KB)

Do I need to load any thing else in the flash ROM ?
I don't want to have kernel image on the ROM,


Regarding the kernel image, I want to have IDE connected Harddisk where
the linux Operating system is installed. i.e., I want to enable the IDE
option and boot from the OS present on the hard disk.

Is it possible to do it using 256KB? 


Thanks,
Siva

My Makefile.seting file (Not complete):

export PAYLOAD_SIZE:=458752
export ROM_IMAGE_SIZE:=65536

export XIP_ROM_SIZE:=0x10000
export ZKERNEL_MASK:=0x3ed
export ZKERNEL_START:=0xfff40000
export _RAMBASE:=0x00000800
export _ROMBASE:=0xffff0000
