Thanks, i will try that tomorrow but i do not have an good feeling about it. (but then it is , my mistake ) If this is not working i will proceed with the installation of the optiplex 790 and see how far i get with this machine. i tried to create an usb drive for it but no succes yet..

Thanks for the replies, what is the IM download site? The second solution you mentioned was to boot the system with an bootable windows cd or usb and then execute the steps you described , but what do you mean by reformat it? And is that all what i must do.?

Hi i installed today by mistake the clover bootloader on Dell Precision 490 desktop witch had the chameleon bootloader active and working. I have Yosemite 10.10.4 installed on it. My systems boot up now with the clover loader and hangs. Is there an way to correct this? Can anyone tell me how to solve this issue? Thanks in advance.

Hi i just successful installed Lion on this laptop using an bootcd with Lion installed for this occasion. Laptop is booting up nicely with working keyboard and usb ports so i can use an usb mouse. Not working is the intel GMA 4500 MHD graphics card, Intel Gigabit cable network and audio. Wireless is no problem because i can install an usb wireless device for this. I could use some help particularly with the graphics card so if anyone could help me with this Thank you and greetz,

Hi thanks for the fast response again wireless is no issue for me because i can use an usb small wireless card which works perfectly on my 430 and 830. My concern is how to boot and which extra to use? Must i use Myhack or something else? Hope you can help me with that Thanks and greetz,

Hi guys i am an possession of an HP Elitebook 2530p on which i want to install Mavericks on it. Can you assist me while trying doing this? In the past you helped me out with several other laptops D430 D620 D630 and D830 and one Precision 490 last month. I attached the specs of this machine ans several screen shots. I hope this will work fine too. Thanks and greetz.. Hp_Elitebook-2530P.txt

Hi major break true ( also for me ) I manage to get the system up an running. First i disabled both PATA drives who were being used by two DVD - DVD writer players.. I saw that the bios settings changed and perhaps that made it possible to make the SSD data drive bootable. No problem what so ever now. I also replaced the present DSDT file installed on the desktop.. I replaced that one by another one witch i downloaded from an site ( i think insalecmac ) from an installation of ML on an Precision 690. Everything works fine now (YES) I also installed the audio kext ( voodoo) so audio also works. Leaving me only one question -- is the installation 100% succeeded? Is there away to check if everything is fully operational ? Greets..

Small status update Wheni boot the system with usb stick and select my mavericks sad drive, i do not have to use the -v flag anymore. Just selecting ssd and desktop boot all the way quit fast.. But still needing usb stick for boot When i tried to boot normally using flag -v -x i am able to boot in safe mode and login Whin i tried to boot normally using flag -v the script stops by message -still waiting for root device-

Thanks any help is appreciated and needed . I will test everything with hopefully aan good outcome. I still need to boot with usb stick and flag -V even when i tried this morning to use the chameleon wizard and update chameleon 2266 checked if SSD drive is the boor drive, and run MyFix Full and checked in Disk Utility the permissions ( witch were corrected by the way ) I still must use the usb stick an flag -V Main concern is the bootloader and every thing to increase the performance will be appreciated Greets..

I checked the fakeSMC version ( installed on my desktop ) version 4.0 of 24-11-2012

Hi all, Status now is I created two myhack usb sticks: one with ML installed using an EXTRA file from Rosmaniac earlier in this topic.. I also created an usb stick with Mavericks with the same EXTRA. Both installations are going well without any problems or error messages.. When i tried to boot the system normally i get an grey screen with an spinning star and after that an stop sign , So that is not good.. When i tried to boot, using the usb stick selecting the SSD drive and use flag -v -x i can boot the system however i end in the safe modus.. and then i see the desktop of ML or mavericks.. I made an screendump of the extensions installed on the system ( mavericks) and the *.plist for more info.. For me i would be very nice if i can get the system boot normally without delays and not with the safe mode option activated. I do not now how to solve this and need experts for this If i have to provide you with specific info please tell me because i am on an dead end.. Sorry Extra.zip

Thanks, this worked network card is up and running (one left one to go ) Bootloader installing I am gathering some info for myself and you ( how i install what i use and what is the problem after that). greetz.

Tell me what you need and i will try to provide you with info . My main concern now is to get my broadcom BDM5752 to work and also that my system boot with an chameleon package. The Nvidia FX4600 works fine with mavericks that one less to go.. Audio works with the tip from you an topic earlier. Then for me i have an working spare model working with mavericks in case my MacPro decided to switch off permanently ( witch i hope will not happen ) Greets an thanks.

Hi Thank you for the reply and useful tips, however i myself do not have the knowledge to create an EDP bootpack so i visiting the osxlatitude site for useful tips and software and in this case i came out on an other site. Because my 490 is not supported yet i have to search for the internet for suitable kext for my internal devices.. I created an list of hardware ID's and name shown above and if needed i can give more information so someone?? can create an bootpack for this machine. For now i just need an working network kext and an working bootloader then it works by me.. Greets.

Hi i found on the internet an suitable kext for my 490 network card < but is is not an pkg or dmg file ( just content ) see attachment. Can you explain to this newby how to install or add this file into my system? Greets and thanks.. Contents.zip

Thanks for all the tips I will try this tomorrow and keep you informed Hopefully I also get the FireWire device working !.

Last step is install a working BootLoader , Audio, Network, Firewire ?? but i do not know how since i do not have an EDP set. my specs are included in this topic. Who can and will help me out? Then i have this beautiful machine working Host bridge [0600]: Intel Corporation 5000X Chipset Memory Controller Hub [8086:25c0] (rev 12) PCI bridge [0604]: Intel Corporation 5000 Series Chipset PCI Express x4 Port 2 [8086:25e2] (rev 12) PCI bridge [0604]: Intel Corporation 5000 Series Chipset PCI Express x4 Port 3 [8086:25e3] (rev 12) PCI bridge [0604]: Intel Corporation 5000X Chipset PCI Express x16 Port 4-7 [8086:25fa] (rev 12) PCI bridge [0604]: Intel Corporation 5000 Series Chipset PCI Express x4 Port 5 [8086:25e5] (rev 12) PCI bridge [0604]: Intel Corporation 5000 Series Chipset PCI Express x4 Port 6 [8086:25e6] (rev 12) PCI bridge [0604]: Intel Corporation 5000 Series Chipset PCI Express x4 Port 7 [8086:25e7] (rev 12) Host bridge [0600]: Intel Corporation 5000 Series Chipset FSB Registers [8086:25f0] (rev 12) Host bridge [0600]: Intel Corporation 5000 Series Chipset FSB Registers [8086:25f0] (rev 12) Host bridge [0600]: Intel Corporation 5000 Series Chipset FSB Registers [8086:25f0] (rev 12) Host bridge [0600]: Intel Corporation 5000 Series Chipset Reserved Registers [8086:25f1] (rev 12) Host bridge [0600]: Intel Corporation 5000 Series Chipset Reserved Registers [8086:25f3] (rev 12) Host bridge [0600]: Intel Corporation 5000 Series Chipset FBD Registers [8086:25f5] (rev 12) Host bridge [0600]: Intel Corporation 5000 Series Chipset FBD Registers [8086:25f6] (rev 12) Audio device [0403]: Intel Corporation 631xESB/632xESB High Definition Audio Controller [8086:269a] (rev 09) PCI bridge [0604]: Intel Corporation 631xESB/632xESB/3100 Chipset PCI Express Root Port 1 [8086:2690] (rev 09) USB Controller [0c03]: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #1 [8086:2688] (rev 09) USB Controller [0c03]: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #2 [8086:2689] (rev 09) USB Controller [0c03]: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #3 [8086:268a] (rev 09) USB Controller [0c03]: Intel Corporation 631xESB/632xESB/3100 Chipset UHCI USB Controller #4 [8086:268b] (rev 09) USB Controller [0c03]: Intel Corporation 631xESB/632xESB/3100 Chipset EHCI USB2 Controller [8086:268c] (rev 09) PCI bridge [0604]: Intel Corporation 82801 PCI Bridge [8086:244e] (rev d9) ISA bridge [0601]: Intel Corporation 631xESB/632xESB/3100 Chipset LPC Interface Controller [8086:2670] (rev 09) IDE interface [0101]: Intel Corporation 631xESB/632xESB IDE Controller [8086:269e] (rev 09) SATA controller [0106]: Intel Corporation 631xESB/632xESB SATA AHCI Controller [8086:2681] (rev 09) SMBus [0c05]: Intel Corporation 631xESB/632xESB/3100 Chipset SMBus Controller [8086:269b] (rev 09) PCI bridge [0604]: Intel Corporation 6311ESB/6321ESB PCI Express Upstream Port [8086:3500] (rev 01) PCI bridge [0604]: Intel Corporation 6311ESB/6321ESB PCI Express to PCI-X Bridge [8086:350c] (rev 01) PCI bridge [0604]: Intel Corporation 6311ESB/6321ESB PCI Express Downstream Port E1 [8086:3510] (rev 01) PCI bridge [0604]: Intel Corporation 6311ESB/6321ESB PCI Express Downstream Port E2 [8086:3514] (rev 01) VGA compatible controller [0300]: ATI Technologies Inc RV630 [Radeon HD 2600XT] [1002:9588] Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express [14e4:1600] (rev 02) FireWire (IEEE 1394) [0c00]: Agere Systems FW322/323 [11c1:5811] (rev 61)

Hi first attempt with the my hack 3.3.1 and an generic bootpack failed ( see attachment) Any idea what i can use for bootpack? i removed the nvidia card and places and ati 2600 xt MAC compatible card so that cannot be the problem. Removal of one of the two hard disk perhaps? Greetz

Thanks i will add the extra file into myhack 3.3 usb stick and see how far i get. I will keep you posted

Hi all The video cards switch is no problem I have two ati compatibel cards on stock Shell I remove the raid partition and install it first on an straight and simple system?.. Greets.

Hi what kind of bootpack you advise to use for bootpack? so i can create an suitable usb boot stick?? Greets..

Hello i just created an list of the specs of my Precision 490. I hope there is enough information for you guys. If needed, I can swap the video card for an ATI 5770 that will work 100%. I hope the machine will work also under Mavericks. Dell-Precision-490.txt Screenshots-490.zip

Hi all first thanks for all tips.. And Herve you are right . I started a couple of months ago an topic about the 490 of mine. Because i could not produce an suitable list of specs and mavericks on my d830 was more important I used an low profile.. But since my d830 works fine now , I have an new challenge this desktop running on mavericks!! Next week I will come up with the specs list Greets...
