We define Dynamic Host Configuration Protocol (DHCP) options being
used by Preboot eXecution Environment (PXE) and Extensible Firmware
Interface (EFI) clients to uniquely identify booting client machines
and their pre-OS runtime environment so that the DHCP and/or PXE boot
server can return the correct OS bootstrap image (or pre-boot
application) name and server to the client.

Re: Request : Client System Architecture Type Option Definition
More and more there computers that use UEFI.
The only way I have found to distinguish them using: Client System Architecture Type Option Definition (93)
If DHCP package 93 we get: 0000 - this will be the BIOS 'basis
If we get DHCP package: 0009 - it will be the basis for UEFI :
or more :
Mikcrotik - please please please, Do It
It wil be best solution PXE function for multiboot.
People are looking for the answer to distinguish the BIOS and UEFI boot.

Re: Request : Client System Architecture Type Option Definition
I know this is old, but i would like to see it done. I have both UEFI and legacy boot on my network and so far the only possible workaround is to change the file manually at the tftpd server.
Re: Request : Client System Architecture Type Option Definition
Two years are waiting, is there any way to implement it?
Re: Request : Client System Architecture Type Option Definition
Any solution?
I think so, because I managed with these configurations, boot via legacy and uefi in a virtual machine, without having to manually change the d boot file.
