I do not understand why you need to change the MAC to use DOS.
The two are not related.
The only reason for changing a MAC is to clone or h(at)ck something.
The MAC it just a unique HW Id to use the Ethernet Port.
If you want to boot a PC into DOS and use TCP/IP.
Then you need a NDIS Driver, NWLink and a Packet driver if i remember correctly. You then need a application to use it with.

If you want a DOS Web Browser then look at:

Hi,
My software is in DOS and used only MAC adresse number, not TCPIP.
if the motherboard with the integrated network card fails, I want to put another motherboard with another network card and have the MAC address of the first motherboard.
So it should rewrite the MAC address in the Drive of the new network card of the same brand.
Thank's

So it is a case of moving the identity. (Cloning).
You need to supply much more information.
The hardware you have, model, partnumber, links to the spec.
You can usual change the MAC, but it not always easy and offen required hacking the MAC PHY EEPROM.
You need to first find the Ethernet Controller, there is uaually an EEPROM next to it. Something Like 93CXX. Sometimes tools are avaliable from the vendor of the Controller that allow you to reprogram the EEPROM. Oherwise you need to directly connect to it, which may required removing it and use a EEPROM reader/progammer.
You then need to find the MAC in the EEPROM memory and alter it.
The big problem here is the chip may also have a CRC to protect againist Corruption or alteration. If I does, you will need to recreate the CRC. This can take some working out.
