Ok, first time poster, long time reader. I have a Clevo D900T mobo based laptop. These were only ever produced with p4 5xx series chips, but the chipset (ICH6) supports the 6xx series. Because it was never produced with a 6xx cpu, a bios was never released that supported things like EIST or EM64T. EM64T worked fine, out of the box. EIST did not (due to no SSDT tables with PSS/PCT/PPC methods). I was able to get EIST working with a hacked-up DSDT, but I'm curious if I'm doing everything I should. Intel CPU Spec: http://processorfinder.intel.com/details.aspx?sSpec=SL8Q7 Intel Data Sheet: http://download.intel.com/design/Pentium4/datashts/303128.pdf Right now, I just have 2 C States, for 3.0Ghz and 2.8Ghz. It's my understanding that these are the only speeds EIST can do in this CPU. now, the questions: 1. Is there something I should be doing with a _CSD type entry in my CPU{0,1} entries to signify that they're HT? 2. How can I verify that EIST is actually working? 3. How do I determine VID values? a. I've just lowered VID 1 by 1, loading the system until it became unstable, at which point I added 1 and called it good b. Is there any advantage to multiple VID's with 1 VID? IE: 3ghz@xxxxx, 3Ghz@xxxxx 4. in the PSS table, the first entry (3000,2800 in my case), are those just for show? 5. Are there additional features the CPU supports that, due to bios limitation, I should enable this way (C1E?) outline of what I've done: http://pat.erley.org/Other/P4EISTSSDT Pat Erley -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
