Also, not forcing it to use PIO mode, it always failed to operate. I would love to test on Alpha, and give you feedback about a fix/finished implementation of the driver. I have both Alpha Server DS20E and Alpha Personal Workstation 500 including that freak chipset. Let me know if/when I can help with my limited capabilities. btw, here is the lspci of the Compaq PWS 500au: snow / # lspci 00:03.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 30) 00:07.0 ISA bridge: Contaq Microsystems 82c693 00:07.1 IDE interface: Contaq Microsystems 82c693 00:07.2 IDE interface: Contaq Microsystems 82c693 00:07.3 USB controller: Contaq Microsystems 82c693 00:0b.0 Multimedia video controller: 3Dfx Interactive, Inc.
