get DHCP/Option#67 inside a script

[IBIT.ZEE]

Inside a script...

How can I get the "Boot File Name" passed in DHCP option 67

in this case can be "ipxe.efi", "undionly.kpxe", "ipxe.lkrn", etc. etc.

what about ${67} or ${filename} also run the config command and see what pop up

[IBIT.ZEE]

hi nikize.... that option gives me the script name...
I want to know the name of the ipxe file
that executed the current script (ipxe.ipx, snponly-x86-64.efi, undionly.kpxe, etc. etc. )

better,,,
I just want to know (inside the script) if the current boot
was originated from BIOS or from EFI firmware
(i dont really need those ipxe file names...)

[NiKiZe]

Did you try config command?
Hint there is platform containing pcbios or efi

[IBIT.ZEE]

yes...
that was what I used
(when i realized i cannot grab the executing ipxe file name)

the snippet created is:

iseq ${platform} efi && set xPLT EFI ||
iseq ${platform} pcbios && set xPLT BIOS ||
isset ${platform} || set xPLT Unknown
