PCI network cards crash VM with general protection fail on boot on MacOS build

My setup consists of Win98 SE installed with a Gigabyte GA-5AX motherboard and Pentium MMX 233 with 128MB RAM. ANY PCI network card I have tried to use causes the system to crash with a general protection fault as soon as the Windows 98 splash screen shows up. ISA ones so far work fine but I would like faster speeds if possible.
