build file for diskonchip

Hi members!
Who can help me to make proper ifs build file for DoC? The problem is to make system (qnx 630) read rc.local while booting from DoC (diskonchip2000, msystems). Default .buildfile doesn’t look at sysinit. I suppose I have to include something like “diskboot…” but don’t know how to do it proper… Please teach me…
This is the doc build file:

[virtual=x86,bios] .bootstrap = {
    startup-bios -Nmachine-name
     PATH=/proc/boot:/bin:/sbin LD_LIBRARY_PATH=/proc/boot:/dev/shmem:/lib:/lib/dll procnto 
[+script] .script = {
# Start up some consoles
	devc-con -n4 &
	reopen /dev/con1

	display_msg QNX-6.2 boots from M-Systems DiskOnChip 
# Start the pci server
	pci-bios &
	waitfor /dev/pci

# DiskOnChip driver
	devb-doc blk automount=hd0t77:/ &

# Wait for a bin for the rest of the commands (up to 60 secs)
	waitfor /bin 10

# Some common servers
	pipe &
	mqueue &
	devc-ser8250 &
	devc-pty &

# Start a debug server for debugging programs
	waitfor /dev/ser1

# These env variables inherited by all the programs which follow

# Start some extra shells on other consoles
	reopen /dev/con2
	[+session] sh &
	reopen /dev/con3
	[+session] sh &

# Start a high priority shell just in case....
	reopen /dev/con4
	[pri=25 +session] sh &

# Start the main shell
	reopen /dev/con1
	[+session] sh
#	[+session] login -p

# Cheat and make the /tmp point to the shared memory area...
[type=link] /tmp=/dev/shmem

# Programs require the runtime linker ( to be at a fixed location
[type=link] /usr/lib/

# We use the "c" shared lib (which also contains the runtime linker)

# Just incase someone needs floating point...

# Include the socket library

# Include the disk files so we can access files on DiskOnChip

# filesystem required shared libs

# Include a console driver

# Include DiskOnChip driver

# uncomment to include IDE hard disk driver, so you can access files on hard disk
# devb-eide

# Include pci server

Try adding “ksh -c /etc/rc.d/rc.local &” to the script
