PCMCIA 3Com 574 can't initialize

[Ingman21]

Hello all,
I hope someone can help. I've been racking my brains out for a while. This boot disk was given to me to modify but I haven't had any help from anyone. I've tried to add in the 3Com 574 PCMCIA drivers but I get an error. This is my error:
'3Com-Megahertz 574 LAN PC Card Dos NDIS Driver v1.2.003. Warning: 3Com-Megahertz 574 LAN PC Card could not be configured using Card Services. No Card Services or Card Services is not responding. Driver will now try to enable 3Com-Megahertz 574 LAN PC Card using PCMCIA host hardware. (Note: Can be forced with PCMCIA_ENABLER=YES/NO keyword in protocol.ini. Error: Enabler failed. Network adapter not found or not reesponding.
Error: Initialization failure. Driver will not be installed.

Ive fixed this as I get this message now:

3Com-Megahertz 574 LAN PC Card configuration using hardware enable succeeded. 574 PC Card is configured. INT=A, I/O=300.

I gotten past this, but how do I get rid of the message? I've tried all sorts of memory address exclusions but cannot find the right now.

Also, after getting past this part, I get:

LOAD ERROR: NO DPMI MEMORY

Any suggestions? Thanks in advance.
