When kernels 2.6.28.4, 2.6.24.3, etc., don't enable DMA on Intel ICH7M chipsets, it is my fault for trying to use WRITE_DMA. I am leaning towards reverting to kernel 2.6.20, because there was a Slax distribution for it, it enabled DMA on Intel ICH7M chipsets, and on other machines where ICH7 presented a SATA interface its LIBATA could access LBA sector address 0x0fffffff. I've been told (can't test personally) that 2.6.20 had trouble with AMD chipsets, but Intel users outnumber AMD users. I probably have to rebuild that Slax with TASKFILEs enabled and see if they work. -------------------------------------- Power up the Internet with Yahoo!
