Hmmmm... yucko. Does the bios have a setting for either "Plug and Play OS" or "Supported OS" or something like that. Although, you dmesg looks OK and it finds the usb and pcm stuff fine ... grrr. It looks like the ISA bus isn't being properly handled on this machine. You might also want to see if there is a windows config utitity for these boxes (IBM has one for some Thinkpads that diddles with NVRAM settings that let config the irq and port for the serial devices and enable/disable them). Do you have the latest BIOS (rompaq) for this machine? What happens if you take out the smbus stuff? : > (Although this is being recognized by adding : > : > options PNPBIOS : > : > to the kernel config and replacing all the device sioN at ... with : > just one "device sio" : : Tried that, but then it doesnt find any sio interface. I put the dmesg (18k) : on http://defiant.vmunix.org/~torstenb/dmesg-pnp-verbose. : But that reminded me to do a pnpscan -v on the bootprompt.
