I have been having a blankscreen and debian lenny scan at boot time.
I believe its a hardware issue(old pc, and just having fun).
What I want to do is to minimise startup scripts to its barest possible
as a workaround by using rcconf.Can someone please help me with this.
my rcconf has the following entries:
acpid
alsa-utils
anacron
atd
bootlogd
bootmisc.sh
checkfs.sh checkroot.sh
console-screen.sh
cron
dbus
exim4
gdm
glibc.sh
hal
halt
hostname.sh
hwclock.sh
hwclockfirst.sh
ifupdown
ifupdown-clean keymap.sh
killprocs
module-init-tools
mountall-bootclean.sh
mountall.sh
mountdevsubfs.sh
mountkernfs.sh
mountnfs-bootclean.sh
mountnfs.sh
mountoverflowtmp
mtab.sh
networking
portmap
procps
rc.local
reboot
rmnologin
rsyslog
sendsigs
single
stop-bootlogd
stop-bootlogd-single
sudo
system-tools-backends
udev
udevmtab
umountfs
umountnfs.sh
umountroot
urandom

Thank you.

I prefer using sysv-rc-conf from the command line. Then you just use the spacebar to check/uncheck services. Note that by default, Debian boots to runlevel 2, but all runlevels 2-5 are the same until you customize them. Of course, runlevel 0 is for HALT (i.e. shutdown), runlevel 1 is Single User Mode (recovery console), and 6 is for Reboot.

That list looks like a pretty minimal list to me, but you could disable some services one at a time and reboot to see what the effect is.
