Hi, concerning a NeoMagic cards, I would like to share my own observations. I own a Siemens Scenic Mobile 510 AGP notebook, that is equipped with video+sound combo called NeoMagic 256 AV. This card is not very well supported by the Linux as of time because the manufacturer does not release any specs. Anyway, I found out, that the video card runs nicely under SVGALib as a VESA card. Even the tweaked modes like 400x300 work! I do not have any experiences with X as I do not use it. Now to the sound: there is a driver for a NeoMagic sound card in a Linux Kernel, but it works only for the 'genuine' cards with ACL97 chipset. But my card was not compatible with this driver. The commercial OSS drivers seem to support the card in a right manner, but I haven't tried. There are also some compatibility modes (8bit SB, MSS) which didn't work too. The only message I've got using any of these was: Interrupt test on IRQ5 failed - Probable IRQ conflict. Accidentaly, loading one module after another the card started working! I tried that several more times until it turned out, that the right sequence is to load a soundblaster module, that will fail. And then immediatelly a module for OPL3-SAx, that will initialize correctly! This way you get 44kHz, 16bit sound instead of a crappy 8bit. I do not understand why it is so, but it works. Below is my sound.sh. The values may not be the same for your machine, try to look into the Windows driver settings or in a Bios.
