well, it's in kixtart 2.33 16bit version.

but, from
http://home.wanadoo.nl/scripting/index.htm
you can find smbios.exe
it's a good tool for hardware stuff on dos.
you don't get there info about mac (if it's not exposed by bios) but you get more specific:
quote:

Structure: Processor Information (Type 4)
Type: 4
Length: 20h
Handle: 0004h (4t)
Socket Designation: 'Socket 370'
Processor Type: 03h (Central Processor)
Processor Family: 11h (Reserved for specific Pentium versions)
Processor Manufacturer: 'GenuineIntel'
Processor ID: ..............
Processor Version: 'Pentium(R) III'
Voltage: 5V:No, 3.3V:Yes, 2.9V:No
External Clock: 100 MHz
Max Speed: 800 MHz
Current Speed: 800 MHz
Status: 41h (CPU Socket Populated, Status Enabled)
Processor Upgrade: 04h (ZIF Socket)
L1 Cache Handle: 09t
L2 Cache Handle: 10t
L3 Cache Handle: -1t (no L3 handle)

the processor id is unique so you can have 20 network cards and macs but this is const.

to get it from list I use:
smbios /g 4|find "Processor ID:"

anyway, if you want to use that address macro it really is the in dos environment.

cheers,
