Hi,

My new laptop (HP Omnibook 6100) has an internal PCI sound card, an ESS 
Allegro-1 (vendor=0x125d, dev=0x1988), but kldloading the Maestro3 driver 
gives:

    pcm0: <ESS Technology Allegro-1> irq 5 at device 3.0 on pci2
    pcm0: unable to allocate register space
    device_probe_and_attach: pcm0 attach returned 6

and there's no output relating to the Maestro3 driver from /dev/sndstat,
although 'kldstat' shows 'snd_maestro3' loaded. 

Loading the module before booting seems to make no difference. The speakers 
sort of crackle (e.g. on PCCard insertion/removal), like they're trying to 
make some
sound - but they don't...

Inserting print messages into the driver makes it clear that it's the attempt 
to allocate SYS_RES_IOPORT that is failing.

There's no option in my (Pheonix) BIOS you can set to indicate that this isn't 
a PNPOS, as some have suggested to others, and PNPBIOS doesn't make any 
difference (as this is a PCI device, but I tried it anyway).

Everything else on this laptop works great (with some frobbing) - can anyone 
suggest anything I can try?

Cheers,

AS
