In ide-dma.c one reads: * Some people have reported trouble with Intel Zappa motherboards. * This can be fixed by upgrading the AMI BIOS to version 1.00.04.BS0, * available from ftp://ftp.intel.com/pub/bios/10004bs0.exe * (thanks to Glen Morrell <[EMAIL PROTECTED]> for researching this). Which suggests, that a faulty BIOS can cause problems with IDE Bus-Mastering, that are impossible to fix (at present at least) otherwise but by upgrading the BIOS. Then, I think, you can add one more problematic board to the list - Intel Aladdin (in other sources Morrison64) aka Advanced/AL and no BIOS upgrade, fixing the problem available (at least I was not able to find one, the latest tested being 1.00.04.CA0). In particular the problem is - impossible to turn IDE DMA on. At least this is my current understanding. At least I was unable to turn IDE DMA on with the help of many of the net-folk. However, some tests suggested (although not 100%) that Win* was able to do this... Cheers Guennadi ___ Dr. Guennadi V.
