dnsmasq to dhcpd translation

[dennisN86]

I'm looking into the deployment of a flatcar Linux instance in my network. The server should be pxe booted.
While I have some nodes installed via OpenBSD pxeboot, which is working fine with explanation of the man pages and help from this forum, I am now trying to pxeboot a board with an UEFI bios on it. The majority of the documentation on how to boot flatcar linux via pxe covers the usage of dnsmasq. Wanting to use OpenBSD dhcpd, I need to translate options like:

pxe-service=x86PC,"Network Boot",pxelinux

To be able to boot UEFI hardware, several options have to be set. Anyone has experience with booting such hardware via pxe and could help with the setup of dhcpd to tackle those issues?

Dennis, I happened across this text in the dhcp-options(5) man page, which may help:

     The documentation for the various options mentioned below is taken from
     the IETF draft document on DHCP options, RFC 2132.  Options which are not
     listed by name may be defined by the name option-nnn, where nnn is the
     decimal number of the option code.  These options may be followed either
     by a string, enclosed in quotes, or by a series of octets, expressed as
     two-digit hexadecimal numbers separated by colons.  For example:

           option option-133 "my-option-133-text";
           option option-129 1:54:c9:2b:47;

     Because dhcpd(8) does not know the format of these undefined option
     codes, no checking is done to ensure the correctness of the entered data.
