Description ralph 1999-07-20 20:15:11 UTC

hello,
  i was wondering if you have a driver and/or support
information for the Neomagic Magicmedia 256AV video/audio
chipset?  im running one of the new Sony VAIO Z505SX
superslim notebooks with RedHat Linux 6.0 on it.  the video
seems to work great at 1024x768...  the previous vaios use
a sb16 compatible chipset (which im sure all of you already
know :)  any ideas what i can do?

What does lspci and/or pnpdump say?

Comment 2 ralph 1999-07-20 20:41:59 UTC

lspci relevant<sp> information:
00:08.0 VGA compatible controller: Neomagic Corporation [MagicGraph
256AV] (rev 20)
00:08.1 Multimedia Audio Controller: Neomagic Corporation: Unknown
device 8005 (rev 20)

pnpdump:
# No board found

OK. There isn't a native driver for it, however, you can try the
following:

The NeoMagic sound emulates a WSS (AFAIR); so you could try:

modprobe ad1848 io=0x530 irq=<irq that the card uses, use lspci/cat
/proc/pci> dma=1

and see if that helps; the last ditch version would be:

modprobe sb io=0x220 irq=<some irq> dma=1

The main problem would be discovering the card's settings - booting
to Windows could be helpful.

Please be aware that we are currently working on making this
available.  At this point in time, we are unable to anticipate the
release date of this driver.  Please check back with  us on a later
date.
Thank you for your inquiry.

, the settings you suggested did not work , i didnt not load windows
at all on this notebook, (was planning on returning it :)

the pci sound card is on irq 9 , not sure of the io

Unfortunately, we really can't support this card until a specific
driver is written for it. Probably the only way you could currently
get it to work is to warm boot from dos after loading compatibility
drivers there.
