| |
Hi,
unlike the 2.2 the new 2.3 kernel skip the probe for PS/2 Mouse if the bios has already detected it, maybe this is good.
Skipping that function PS/2 Mouse is never showed during kernel boot process.
I've wrote a simple patch that correct this and also show the irq where available.
Patch is quite simple and tested only on i386 platform.
ciao, luca
