Subject:   sio problem with FreeBSD 2.2.6
Message-ID:  <361645DD.35124415@neighbour.msk.ru>

next in thread | raw e-mail | index | archive | help
Hello!

I have a problem with FreeBSD 2.2.6 -  the system don't want to see sio ports,
although hardware is configured properly in BIOS. It says:

sio0 not found at 0x3f8
sio1 not found at 0x2f8

Can you help me to solve this problem?

My hardware:

CPU: Intel Pentium-133
Mainboard: Iwill P55XB2 (Intel TX chipset)
           Two onboard COM-ports configured as:
           * COM1: 0x3f8/IRQ4
           * COM2: 0x2f8/IRQ3
Video: ATI XPERT@WORK (I have tried to use another card and it takes no
effect)

My kernel:
