I have a IBM ThinkPad 345C with IBM Credit Card Ethernet II Adapter (P/N: 42H4916). My goal is to get an access to my local FTP server. I had no issue with installing driver for the adapter and TCP/IP-32 v.3.11b for TCP/IP support. Device have original IBM preload installed (PC DOS 7.0 + WFWG 3.11) including PCMCIA management application (IBM PC Director), so I have no issues with the resources management. Also IBM test application reports no issues with adapter. When system BOOTs, driver automatically allocates resources for the device (it reports it) and status LEDs on switch starts to blink. However, once WFWG 3.11 will load, I have still no access to the network. Device is not able to get IP address from DHCP. Configuring static IP address also didn't help.
After some time I've found, that device doesn't get adapter's MAC address, however I have no idea what could cause such an issue. Novell NetWare (IPX) had no problem with getting MAC address. I also tested this adapter with Windows 95 and Windows 98SE (different device) and haven't experienced any issues.
The question is - how to debug such an issue? Maybe someone has experienced it in the past and know how to solve it?
