DHCP server bootfilename how to add

Hi friends,

I am trying to setup iVentoy as my network boot server and I have Mikrotik as DHCP server in my LAN. As per instructions I need to add next-server option “Set next-server option value to the iVentoy IP address in the third-part DHCP server.” This it not a problem.

But next request is to add boofile option “For External mode, set bootfile option value to iventoy_loader_16000”

I can see tab Options under DHCP in RouterOS, but when I try to add such option, I need more code, I found under IANA documentation that it is 67 - BootFileName, and when I try to add I got information “Couln’t add that DHCP option - Unknown data type” (see picture)

Can you advice?

many thanks
