Hello everyone, I'm using one HP dx7300 PC and the motherboard is based on intel 965G with ICH8. I setuped Red Hat AS3 update9 successfully but my SATA H.D was recognized as /dev/hda, which model is 'Barracuda 7200.9' produced by Seagate. When I run hdparm -d1 /dev/hda, get such info: HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) How to enable the DMA mode? Either how to recognize the SATA H.D to /dev/sda? Thanks for your help! Have a good day! Regards, Joffre

Check your bios, it should be /dev/sd* for sata, but some motherboards have a compatibility mode that mimics ide (and thus, /dev/hd*). -- ______________________________________________________________________________ | spike1@freenet.co.uk | | |Andrew Halliwell BSc(hons)| "The day Microsoft makes something that doesn't | | in | suck is probably the day they start making | | Computer science | vacuum cleaners" - Ernst Jan Plugge | ------------------------------------------------------------------------------
