This is a well known bug, so don't feel bad :-) You must have missed question 7.10: -- from FAQ at http://www.freebsd.org -- 7.10. The workaround works fine, but now I want to use my serial ports. You'll have to build a new kernel with the following modification: in /usr/src/sys/i386/isa/sio.c find the one occurrence of the string 0x2e8 and remove that string and the preceding comma (keep the trailing comma). Now follow the normal procedure of building a new kernel. -- end -- More detail: in 2.1-RELEASE, it is line 342 (or somewhere near there :). It should read as follows: static Port_t likely_com_ports[] = { 0x3f8, 0x2f8, 0x3e8, }; Recompile, resintall, reboot, enjoy. > I have tried removing the 3c509, replacing the serial ports with true 8550 Uarts, > and replacing the ATI adapter. I sure hope you put 16550s back in... Remember that 3.1.2B has expired; you'll have to use 3.1.2D, which is working just great here.
