mkisofs problems and booting the cd

It's like this, i'm trying to compile a cd with mkisofs under linux for the simple reason that i want to have a few "odd" bootoptions.

• Unattented OEM setup (so it copies a few files from the $OEM$ folder
  
• Unattended normal setup, does not copy files from the $OEM$ folder
  
• Normal setup, no $OEM$ files
  

They way i see it is to duplicate everything, i386 folders, $oem$ folders, etc...

and that's what i'm to get skip by using linux, symblinks and the -f option in mkisofs (follow folder, or something like that)

Also, i'm using cdsh for a nice menu.

I've tried a lot of different switches for mkisofs but none have so far worked

Maybe i'm hoing about this all wrong, but this is what i do...

compile the cd normaly in linux, open up the iso in ultraiso and add the bootloader, what happens after that is that it runs ok, shows up the menu and just promts me that it can't find the NTLDR....

i'm guessing tha it's somekind of offset problem with the loader or something, if anyone knows a way to fix this please share!
