  1. How did you install Mint? I'll have to do some digging to see how an MBR disk would be detected (and it seems like, from you fdisk output, that it is MBR). On my CentOS multi-boot system fdisk sees this: [[email protected] ~]# fdisk -ul /dev/sda WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal)
  2. Please see the instructions on setting the proper partition type for the linux boot partition in the thread: https://osxlatitude.com/index.php?/topic/5902-dualboot-installing-linux-after-mavericks/ EDIT: And please note that that only applies if Linux is installed to a GPT-formatted disk. If it's MBR, I haven't tried that one, but the correct type for Chameleon to chain boot is in the same source tree that I note in a post in the referenced thread; you'd just have to look through the MBR equivalent to diskScanGPTBootVolumes.
  3. I have seen this with my M4300 as well, when booting the install USB and before installing EDP. But I haven't seen (with the rev 762 EDP and associated bootpack) the keyboard and mouse issue.
  4. On my Precision M4300, very similar to your D830, I had serious audio issues (including the audio not recognizing at all on some boots) until I did the performance optimizations mentioned in the thread https://osxlatitude.com/index.php?/topic/3078-m4300-no-ethernet/ I found that audio would skip and sputter even on those instances when it would load properly; this was with EDP rev 762 on 10.9. And I found it would not load at all (even to the point of not showing the volume control) at least one out of every four boots. Some audio programs triggered worse sputtering than others. When
  5. Excellent. You're very welcome, glad it worked!
  6. You need to have Ubuntu install the bootloader on the partition containing /boot (either the / partition or the separate /boot). You then need to use a tool like GPT fdisk (gdisk) to change the 'type' of that partition to '0700' See https://osxlatitude.com/index.php?/topic/5902-dualboot-installing-linux-after-mavericks/ for more information and a success story.
  7. Glad that worked, and you're very welcome.
  8. devilotx, can you provide the output of 'sudo gpt show /dev/disk0' please? Here's what I get with a working triple boot, where one of the OS's in CentOS Linux: dhcp-pool132:bin lowen$ sudo gpt show /dev/disk0 Password: start size index contents 0 1 PMBR 1 1 Pri GPT header 2 32 Pri GPT table 34 6 40 409600 1 GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B 409640 587423656 2 GPT part - 48465300-0000-11AA-AA11-00306543ECAC 5878
  9. Further note: it appears that gpt might do the same thing as gdisk, under OS X. I have not tried it, and will at my earliest opportunity reboot into OS X to see if that is indeed the case. I'll update this post if a reply isn't posted before..... (Updated to remove pdisk reference, instead it appears gpt is the command to use). Issue 'man gpt' at a terminal command line to get arguments and such, or use the online manpages on the Apple Developer site. EDIT: The technical info: Chameleon (as of SVN 2283 from voodooproject svn) will recognize one of two GUID's for chain booting a
  10. devilotx, I'm assuming first that you installed to GPT instead of MBR. If that's not the case, then this probably won't work for you. Also, note that while I dual-boot Linux, I'm using CentOS, not Ubuntu. So, as the saying goes, your mileage may vary (YMMV). You need to change the partition type of the Linux boot partition to '0700' for Chameleon to recognize it, in my experience. This can be done most easily with a program called 'gdisk' which is available for Linux and OSX. By default, CentOS at least will set the boot partition's type to EF00 (as that's correct when booting
  11. Ok, can do. And, yes, the 690 is on my list. That will need a complete set of new model data, and will be a fun project. Separate threads; I would assume posting results and such in the R&D section......
  12. Bronxtech, I'll do what I can. I understand the time issues, since I've been involved in some open source projects before, including one stint over a period of five years that, when I did step down, a number of people expressed surprise that I had done it all as a volunteer. I also have several children and a full time job, and I understand the pressures, particularly in terms of support (it's amazing to me how pushy people can get for support of a free-to-them nature! I still get e-mail 'demands' for fixes, and I haven't maintained that one package for several years!). Within the f
  13. Hervé, I appreciate the additional information and your great work in these forums. I've only put in the details that I have in order to support my initial assertion: the M4300 with Mavericks felt sluggish with the out of the box EDP build (as of SVN rev 762). It felt slower than my previous D820. And that's the bottom line. It's great that there are customizations that can be done outside EDP, and I thank you for the pre-baked M4300 files. But it does mean I've left EDP behind for anything in the future, as an EDP model build will wipe out what is working so wonderfully right
  14. The point is to illustrate that the EDP default is pretty poorly tuned, at least for M4300. And I'm glad to see change in that on the horizon, and I want to be able to confirm improved performance in the default EDP. After all, one of the draws of EDP over the rest is that there is model data that is supposed to be somewhat tuned for each supported model, no? Incidentally, this isn't meant as a criticism of the project, just a desire to make it better. And when I have my test rig built and in hand, I will be able to hopefully help confirm that what EDP builds for each model really is tu
  15. Ok, in the thread https://osxlatitude.com/index.php?/topic/3078-m4300-no-ethernet/ a set of files are posted, and a bit of discussion occurred about M4300 performance relative to D820 with default EDP, and the extreme performance boost presented by the use of the MBP5,1 SMC and SMBios, along with some other kext changes. Please see that thread for the files, context, and such. Also see the article on performance tuning with FakeSMC and SMBios, http://www.osxlatitude.com/tuning-performance-with-fakesmc-smbios-plist/ Now, I'm getting ready to build my second M4300 into a benchmarking rig,
