Hi. I have problem with com ports. Com1 and com2 work ok, com3 and com4 no. I think I need to change  IRQ . In  BIOS
I have:
COM1 3F8/IRQ4 WORK OK
COM2 2F8/IRQ3  WORK OK
COM3 3E8/IRQ10 DON'T WORK!!!
COM4 2E8/IRQ11 DON'T WORK!!!
how can I configure IRQ for com ports?

irq 10 & 11 are frequently used. Check your machine with

dmesg | grep -i irq

Perhaps reserve them in your BIOS.

With dmesg command I see:

<6>ttyS00 at 0x03f8 (irq = 4) is a 16550A
<6>ttyS01 at 0x02f8 (irq = 3) is a 16550A
<6>ttyS02 at 0x03e8 (irq = 4) is a 16550A
<6>ttyS03 at 0x02e8 (irq = 3) is a 16550A

So, I need to change ttyS02 at 0x03e8 (irq = 4) to ttyS02 at 0x03e8 (irq = 10)
and                  ttyS03 at 0x02e8 (irq = 3) to ttyS02 at 0x02e8 (irq = 11)

In bios I can't change IRQ, disable com port only.
How can I change IRQ in DSL??
thanks.
