IBM 300PL Model 6562-34U. On bootup receive "1852 PCI/PNP error! Not enough I/O space available. If I disable Serial Port B I can bootup. The system installs the second com port as Com 3 instead of Com 2. There is a modem installed on Com 2 even though under Device Manager Com 2 does not exist. How can I get the modem removed so that when the machine boots I can install to Com1 and just leave the other Com port disabled? Currently if I remove the modem the system just reinstalls to Com 2 on boot.
