Syslinux - Aug 2006 - How to enable F12 key to start PXE boot?

I researched on Archive, but the instruction says to copy startrom.com to 
startrom.0,

so I changed boot program to startrom.0 instead of pxelinux.0,  it gives 
me a TFTP error saying file not found. 
then I keep startrom.0, change boot program back to pxelinux.0, then I do 
not see F12 key and boot directly to PXE.
then I change the boot program to startrom.com it asked me to press F12, 
but can not boot into pxeinux.

It seemed to me that I have to configure something else to make startrom.0 
connect to pxelinux.0.

I want my end users press F12 to start the PXE boot, at other times just 
boot from hard drive.

Please help, I believe the answer is some where on the archive, but I 
could not fine it.

Thanks.

Add in your pxelinux.conf a clause like this at the top of the default file:

default hard

and somewhere in the labels:

label hard
  localboot 0
  append SLX=0x202

at the bottom of the default file:
timeout         200

Then by default it exit PXE code and boot onto your next BIOS device, but if 
you quickly promt something, goes into your desired option or if you HIT 
ENTER goes more faster into next BIOS booting device. I have this config file 
since a lot, I can't remember if timeout on pxe is ok.

I use to make nice ascii art message files with colors, if you search the 
list, you can see some editors to put your own pretty text messages, for 
going into PXE options instead of timeout.

Post your pxelinux.cfg file so we can see what you are trying to
achieve.

========================================Below is off topic for this mailing
list.
========================================
If you don't require any menu functionality or ability to load other
OS's etc, just have your DHCP issue startrom.com as the bootfile name.
There's no need for pxelinux.

RIS/WinPE/XPe includes two bootloaders. Startrom.com and startrom.n12.
The latter one doesn't prompt for F12.

Note you normally have to press F12 to make the BIOS PXE boot. You then
use the startrom.n12 so you are not prompted for F12 again.

Startrom.com is mainly for situation where the PC is set to PXE boot by
default and the user isn't required to press F12.

my pxelinux.cfg folder has one file called default show as below:


default boot
prompt 0
say booting....
label boot
kernet memdisk
append initrd=boot.imz

I am using MS remote boot service, and uses pxelinux.0 as the  boot 
program, but I want to enable F12 so end user can skip PXE if no need to 
boot from PXE, whenever needed just press F12 to boot into PXE to restore 
images.

I posted earlier, and got confused by startrom.com and F12, if I use 
pxelinux.0 then I do not see F12 prompt, if I use startrom.com then it 
does show F12, but when press F12 it is looking for winnt.sif, ...

Anyway, some people replied, but I think if I use startrom.com them how do 
I link startrom.com to start pxelinux.cfg default? put it into winnt.sif?

Please help.

You are really confused yourself

The diference between OpenSorce software and closed one, is that you always 
can modify or configure OpenSource to do something else..... If you do not 
want to fix your issue configuring or modifying, try asking M$ technical 
support, they should know how to do it at a reasonably price....
