I ran a program that came with my Xircom PCMCIA Ethernet Card for
identifying the PCMCIA controller chipset. The program reported the
controller was a Cirrus chipset. It is my understanding that this is
compatible with the Intel chipset but I am not quite sure.

Well, I don't know. I didn't see this problem reported in any place. Neither
in the documentation nor in the BBS nor in the FTP site nor in the Tech.
Notes nor in the Fax Tips. Nothing, nothing in any place. I just found this
small utility to clean the CIS.

When I run the utility, the first message I get is one that says "Invalid
checksum found." The it proceeds to clean the CIS.

(I am gonna post all the messages I am getting from the different programs.)

OK, I am gonna try that one.

By the way, I don't have cheap access to 3Com's BBS (it's a long distance
call for me.) What I am doing is using their FTP sites ( I
think it is very new since it is not documented anywhere in my package. Also
they have a WWW server at

See ya.
