UEFI and BIOS

[k_rock923]

Hi all,

I'm a bit confused with what I need to do to make things work with both UEFI and BIOS. I don't have a DHCP server that's capable of presenting different options based on BIOS/UEFI - just the next server and image filename.

Some reading indicates that I might be able to get around this by embedding the script when building - would that script then handle differing images for UEFI/BIOS? If so, what do I use for the boot image in the DHCP configuration?

In case I'm going about this in the completely wrong way, here's what I'm looking to ultimately accomplish:

• Machine (either UEFI or BIOS) boots from network
• Menu option to chain to a local WDS server
• Several menu options to boot Windows Server ISOs (aside from what's available in WDS). From reading, I understand that this might be wimboot?
• Menu options to boot from a few Linux utility discs - mainly just clonezilla
  

I'd like to not have to rebuild the image every time I add an iso so I was thinking I could embed a script that does nothing but chain to a config file on a server that I can edit when needed and essentially not need to touch the built image unless I want to rebuild it with a new version of iPXE later.

Appreciate any help on this.
