Do you see other solutions (the > goal is not to have complicated DHCP/BOOTP server on Windows server)? Use the Broadcom NDIS2 driver (unfortunately, Broadcom doesn't offer a packet driver, but I will work on a generic UNDI driver for the Broadcom 5702 in the near future as soon as I have the hardware available), and replace your current PXE bootrom with the netboot bootrom in the system: for example you can include the netboot bootrom into the system BIOS (possible with Award and AMI BIOS) and either remove the existing PXE bootrom from the system BIOS if it's installed there, or turn it off using the means provided by the manufacturer (using a setup program or something alike). Then you don't need to have a seperate boot file for the operating system. Another approach would be to put the path hardcoded into the bootrom code (it's around line 106 in file netboot/bootrom/kernel/boot/boot.c - you need to rewrite it a little bit) and recompile the whole bootrom. And a third solution would be to wait a couple of months: I'm presently working on mknbi-mgl to generate a boot image file which can be loaded using a commercial PXE bootrom. This way it would be possible to write a small MGL script (just a few lines) which takes an arbitrary, user- defined DHCP tag, or a hard-coded file name if you like, and return it as a boot image file name to the bootrom. Since I'm presently short of time this implementation will still take some time, but initial changes are already implemented. Help is always appreciated... gero. -- Gero Kuhlmann Tollenbrink 18 Groote Gracht 33 email@example.com 30659 Hannover 26723 Emden firstname.lastname@example.org 04921/997561 =========================================================================== This Mail was sent to netboot mailing list by: "Gero Kuhlmann" <email@example.com> To get help about this list, send a mail with 'help' as the only string in it's body to firstname.lastname@example.org.
