I am trying to install a network adapter (I have tried Intel(R) PRO/100+ PCI Network Adapter and Dlink 528 PCI adapter) on a Pentium 133 Mhz PC. However after installation the network adapter status tells me that the driver has not been loaded and the device is not working. I have tried to install it in both Win NT 4.0 and Win 95. I tried changing the PCI slots also. But it doesn't work.
Additional a diagnostic program provided with the Intel adapter tells me that the "Loop back test" failed (other tests i.e. Control Register, Cable test, and the Intel 82558 contoller tests are passing). I am not able to understand the meaning of Loopback test also.
Earliar this PC had been successfully configured with the DLink DE 528 adapter. However for some reason I plugged in a ISA based Texas DSP board. After doing this the netwrok adapters are giving me this problem even if I remove the DSP card. I have tested the network adapters on other PCs and it works fine.
Is there a possibility that some IRQ clashes could be occuring ? Do I need to check some BIOS settings ? Please advice.
