Hello, I installed Mandrake 6.0 some weeks ago. Everything (excepted sound...) works fine, but yesterday I noticed that I am running with DMA disabled (dmesg excerpt reported below). I checked the BIOS setup, and it says something like "AUTO detection of HDD features enabled". The MB is a FIC with VIA chipset, unfortunately I forgot to write it down.. Note: this machine has only MANDRAKE installed: WIN98 was installed by the vendor just to check that all HW was ok, but the whole HDD was reformatted during Mandrake installation. Any idea about why this is happening, and how to fix it? (different configurations, LILO parameters, etc...) Thank you in advance, Marco Fioretti Humour note: at power up, the on board antivirus tells me in great despair that there is some "unknown virus on MBR!!" Eventually, of course, LILO and LINUX takes over.. _________________________________________________________________ DMESG excerpt: Linux version 2.2.9-19mdk ([EMAIL PROTECTED]) (gcc version pgcc-2.91.66 19990314 (egcs-1.1.2 release)) #1 Wed May 19 19:53:00 GMT 1999 Detected 350799006 Hz processor.
