Make a parallel boot block for notebook

Hi:
Can anyone tell me which colored wires from a parallel cable, to join together to make a boot block for a laptop? My bios seems to be fried. I've tried to follow the following from an HP Support forum, but I have too many green wires to pick from (i.e. green with white stripe, green with black stripe, etc). Here is the post from the HP forum:
Boot Block Jumper

I used an old printer cable and traced the wires using a multi meter.

My wires were:-

Red to Black white
White to light Green
Yellow to very light green
pink to orange
brown to red/white
Insulated and cut off the bare parts of the other wires.


The link for this post is:

It's a Phoenix bios and I'm trying to do a recovery.
Thanks.

Get the service manual and look at the actual pins. The wire colors inside a parallel cable are not standardized in any way and just following the colors could lead to a smal cloud of smoke here.

From this post:
The update key is connected to the printer or LPT port. It just connects the pins in a special order.

With a normal 25-pin LPT it connects pin:
2 <--> 15
3 <--> 13
4 <--> 11
5 <--> 12
6 <--> 10
