Phew. Weeks of painstaking work wisked away in one quick BIOS upgrade. I post this for all current and future users of the Dell XPS_Rxxx mother boards. With the XPSR_A9 bios, I found no way to _truly_ disable ACPI (ie. 'Power Managemnet [DISABLE]' did not in fact turn off ACPI.) I upgraded to XPSR_A13, which was tagged on the Dell website as having power management improvements - (ie. "We got rid of the bug.") That done, my system final conforms to some hard real time specs, and my massive glitch is no where to be seen! Heartfelt thanks to all of you who helped me on this project. The list of contributors is long and includes both RTL and RTAI gurus, who were emailing me advice even as they were slashing each other and considering the now forgotten idea of splitting the list. I never voted, but I assure you all that my problem would have taken longer to resolve if I had only been posting to half of you. Healthy disagreement only improves both camps. Special thanks to Steve Cohen, who it appears may have spent more time on my problem than I have in the last couple weeks, and who in the end forced me to accept that it was a power management issue, (as almost everyone had suggested from the beginning), and that perhaps the bios wasn't doing what it said it was doing. Thanks again to all - and be wary of Dell's running older BIOSs. -Chuck -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] --- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
