I would like to thank everyone who helped me here! I am quitting trying to run OSX on this laptop since it's too old and incompatible. I will try again when I get an "not-so-old" laptop. Thank you guys, crc-error404, simeonoff and Zeppo!

Sure I did try it, but this BIOS has the strangest behavior I ever see... If I set the SpeedStep ON = The processor varies from 800MHz to 2.13GHz If I set the SpeedStep OFF = The processor gets locked at 800MHz. Isn't this inverted? What I need to do (by modifying the bios I think, but I don't know how to) is: SpeedStep set to OFF = The processor gets locked at 2.13GHz (this should be the correct behavior, right?) Edit: I just realized that my system can now boot from GPT (it couldn't before I apply the customized BIOS from crc-error404) I also found out why chameleon 2 didn't worked before, and this is how I did to make it work: My HDD is partitioned as MBR, first partition is NTFS and second partition is HFSJ This seems to me that Chameleon is made for GPT, and looks for its files on "disk0s2" (since disk0s1 is the EFI partition, and disk0s2 being the first usable disk) and that's why it didn't worked before, because I was using "disk0s1" as my Mac partition on MBR formatted drive.

@Zeppo My laptop does not boot Chameleon 2 (gives boot0 error) so I am stuck with the previous Chameleon version. I managed to install a nice double-boot Win7+OS X 10.5.7 (using 10.5.5 kernel - I am also stuck with this, since from kernel 10.5.6 and above there is a check for "processor family" value in order that only core2 processor will boot - I mean, I am saying this based on readings through the net) - and my processor is a weak Pentium M (single core, SS2-only), and I am happy to run 10.5.7 on such old laptop) So, now the OS X is working, I only need to get sound+network+video(even tho I think ATI X600 wont work) And I also need to make the processor run at 2.13GHz at boot otherwise I get kernel panic (it says something like this: reported fsb: 133mhz, actual fsb: 49.xx Mhz, cpu0 panic in rtc .....) A temporary fix I did and it works sometimes, is to add -f switch to make the boot read all the kexts, so this makes the processor work, and it goes to full speed and the system boots. All I need (as in "the most important right now") is to find a way to turn off speed step and make the processor always run in 2.13ghz instead of 800mhz minimum speed.

@crc-error404 Man I don't know how can I thank you!!!! I don't really knew how to use the "recover.hdr" file, so I just installed D810-OSX.EXE (using DOS-boot PenDrive) and then rebooted to Windows and now I have HPET (and other ACPI000 unknow device) and this is a sign that is worked!!! :D:D Thank you very very much! @simeonoff I will buy a new pendrive (16gb) tomorrow to try the guide you suggested. During the meantime, I will play with other OSx86 DVDs I have here to see what happens! Thank you very much! Ah, I will be back to post what happened! TYVM again guys Edit: Hi, I'm back!!! I'm still unable to run SL (till now tried with iFail S3) I noticed that things are a bit faster now, but still not perfect yet. (is the HPET that makes things faster?) I'm managed to install iFail v7 (10.5.7) but I'm having some trouble with kernel panic at random times. I also noticed that the SpeedStep implementation on my processor is very inconsistent It varies from 800MHz to 2.13GHz and, sometimes it boots at fullspeed (and then osx boots normally) but other times it boots at 800mhz (and then I get KP) I tried to disable SpeedStep on the bios, but if I do this, this ****ing system locks the processor at 800MHz Is there anyway to change bios to make it always run in 2.13GHz when I disable Speed Step? TYVM in advance.

I added in the file: The BIOS (same I am using right now), DSDT.aml (generated by DSDT Patcher) and dcpdsdt.dsl (the decompiled DSDT). The password is: 1234 d810_a05.rar Thank you very much.

Nobody? :C 

Dell Latitude D810 Processor: Intel Pentium M 2.13GHz (MMX,SSE,SSE2) Memory: 2GB DDR2/533MHz (1GB original infineon + 1GB kingston) Video: ATI Mobility Radeon X600 (PCIE) (1002:3150) Network: Broadcom NetXtreme BCM5751 (14E4:1677) Wi-Fi: Intel 2200/2915 (a,b,g) (8086:4223) Sound: SigmaTel C-Major Audio (8086:266E) Chipset: Intel i915/ICH6 (4x USB Ports) PCMCIA: Texas Instruments (104C:8036) SmartCard Reader: Texas Instruments (104C:8038) Infrared: SMC Fast Infrared (*SMCF010) Bluetooth: No bluetooth (has expansion for Dell BT350) Hard Disk: TravelMate 60GB 7200RPM ATA Optical: Philips DVD/CD-RW Combo ----------------------------- I managed to install OS X Tiger 10.4.8 (JaS) but nothing works (no lan, no wi-fi, no video, etc) I also managed to install OS X Leopard 10.5.7 (iFailv7) but it hangs, takes ages to show login screen, also nothing works. I need help! I want to do with this laptop the same as I did with my desktop computer... On my desktop computer I applied the DSDT patches directly on the BIOS chip, and I don't need to put DSDT.aml on the root anymore, the system works like a charm. I want to do the same with this laptop, but I can't find a way to modify the BIOS. I tried with Phoenix SLIC tool 1.85 that has option to modify the DSDT but the changes aren't really applied for some unknown reason to me. Has anyone sucessfully installed any OS X with everything working on this model?
