CBCOMBO cannot find the memory or port resources to load. The utility needs either an I/O Port Address or a Memory Range to load itself. CBCOMBO either is not checking those resources that are available, or the system bios is not allowing CBCOMBO the resources to load.
CBCOMBO.EXE is the point enabler for the Intel® PRO/100 Cardbus II Mobile Adapter Products. This point enabler provides the software interface between the network/modem adapter device and the system cardbus controller. Without access to the Cardbus controller, the Intel® PRO/100 CardBus II drivers cannot load. This is required for the adapter/modem drivers to load, and the adapter/modem to communicate with the Cardbus Controller and the PCI bus.
Boot to DOS clean, attempt to load cbcombo.exe using various parameters such as :

ALWAYS USE VERBOSE PARAMETER
Try both memory mapping mode as well as I/O mode. Use the "memory=" or the "ioaddress=" for memory mapping mode or I/O mode respectively. Use the nocom parameter if adapter is without modem.
Try to force memory and I/O address and also try reserving memory loading DOS* with emm386.exe and reserving memory. This is done with the X= parameter in the config.sys .Reserve the memory range using the memory exclusion in DOS that you wish to force the CBCOMBO.EXE to use.
