China DOS Union Forum - China DOS Union

hi, hello everyone,
I've recently been writing a piece of software in the DOS environment to read and write a PCI board card, using the PLX9052 chipset. Under Win98 and in the VC6 environment, using outpw to write a word of data to the port works successfully, but under BC3, using outport to write a word to the same port does not work. Testing with instruments seems to show some activity, but the data is wrong. What exactly is going on here? If you have time, I hope you can give me some help. Many thanks in advance, thank you.
