Quoting both of them, respectively:

"
AH = E8h Big Memory size
...
AL = 81h Big Memory Size, 32-Bit Protected Mode
Exit:
Carry 0 = E881 supported
EAX Memory 1 MB to 16 MB, 1 kB blocks
EBX Memory above 16 MB, 64 kB blocks
ECX Configured memory 1 MB to 16 MB, 1 kB blocks
EDX Configured memory above 16 MB, 64 kB blocks
"

and

"
AH = E8h Big Memory size (over 64 kB)
...
AL = 81h Big Memory Size, 32-Bit Protected Mode
(Windows NT 3.1 and OS/2 2.11 and 2.20)
Exit:
Carry 0 = E881 supported
EAX Memory 1 MB to 16 MB, 1 kB blocks
EBX Memory above 16 MB, 64 kB blocks
ECX Configured memory 1 MB to 16 MB, 1 kB blocks
EDX Configured memory above 16 MB, 64 kB blocks
"

As far as the manuals are concerned, E881h is for 32-bit PM.
