Check that it is enabled in cmos setup


Thanks for your fast response.

I suspected that at first and checked. Serial port did enabled (0x3f8, 4). I
disabled it, rebooted. Enabled it again, rebooted. No magic.

I added a comm port manually, again. It was given the name of com4, and
still had resource conflict.
However, I kept it this time (I uninstalled it immediately in previous
trials). Rebooted. com1 appeared. Strange (at least from my view).

Either BIOS or system should be responsible.

Forgot to mention, I was doing kernel debugging, so
.... /debugport=com1 in boot.ini
Don't know if that mattered.

Rebooted once more, com1 disappeared.
