I guess you got the register dump while the cards was in, didn't you ? Just to be sure :) I'm asking this because the latency timer should be 0xC0, not 0x40. > The question is, what registers are likely to be the ones we have to change? Register 0x80 should be 00 (PCI prefetch disabled). Register 0x0D should be C0 (latency timer, the driver should be able to set it, so don't touch it). I don't know about all other registers because I couldn't find any documentation. Registers >=0x80 are chip-specific and they are explained here: http://pcmcia-cs.sourceforge.net/specs/AP476IIE10.pdf -- Giuliano. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
