errr these are msdos.sys settings
check out the webpage
http://www.physiol.ox.ac.uk/~trp/msdossys.html
look at the info on bootwarn, BootMenuDefault, and maybe BootSafe also (info from the url included below)
I would test these out to see if I could figure out what you need from it but I am at work and only have my win2k machine to work with so I cant do that right now.
BootWarn=
Default: 1
Purpose: A setting of 0 disables the safe mode boot warning message and
the Startup menu.
BootMenuDefault=
Default: 1 if the system is running correctly
3 if the system hung in the previous instance
Purpose: Use this setting to set the default menu item for startup.
BootSafe=
Default: 0
Purpose: A setting of 1 forces your computer to boot in safe mode.
