[GUIDE] Mavericks on Dell Latitude E6420

Recommended Posts

Hi Nolen,

your HowTo was exactly the one I was looking for as I am new here. Thank you very much for this.

I have followed successfully all steps to create the boot medium.

Only at Step 6 I was not able to pick the zip file as only folders (Step 7) are allowed if I am right.

 

My system, an unmodified Latitude E6420 with i5-2540M, 8GB RAM and Bios A21, boots legacy from my prepared USB Stick.

But I get the following message after the boot screen disappears:

EBIOS read error: Controller or device error
   Block 0x1d0798 Sector 0
EBIOS read error: Controller or device error
   Block 0x1d0798 Sector 0
EBIOS read error: Controller or device error
   Block 0x1d0798 Sector 0
EBIOS read error: Controller or device error
   Block 0x1d0798 Sector 0

I have tried to get more infomation with the -v flag.

Much pages are shown. Finally the systems stops with (handcopied):

...

I am a complete newbie building OSX on a Hardware System, I only had few virtual OSX's (10.6 & 10.9) running until now.

I have used 10.6 to build the USB Stick.

All BIOS Settings are set to back default, only UEFI is active.

CPU XD Support is switched on.

 

Maybe someone has an Idea how to fix the issue as I like the idea to get OSX on my Laptop :)

 

Thx

Lars

P.S. Sorry for my bad english

 

 

 

Hello,

 

i have the same problem as Lars.

When i boot up my USB stick i will get the same errors as Lars.

I have a Latitude I7, 2,6GHz, 8GB, 80GB HDD for testing, Intel 3000 Graphics, Athertos AR9281 Wifi, Bios A21, System Mavericks 10.9.5.

Re-install your bootloader and try again. Then, try and repartition and/or reformat your USB key. Please note that some keys do not like GUID/GPT partition scheme (I experienced this myself with a couple of cheapo 32Go keys). If you're using GUID scheme, try FAT/FAT32 and vice versa. If you still do not succeed, try a different key. An 8Go USB key from a respectable manufacturer really cost pennies these days.

You need to set SATA Operation to AHCI too.

Hello Herve,

 

will try this.

Thanks.

After making the Mavericks system on the stick i take the e6420 drivers as described in the first post, right?

 

 

@ Jake Lo

I have reseted the Bios to Default Settings and make the extra choice of the AHCI setting.

Jolly Roger,

did you try the bootloader with "-v" as I wrote in post #14 ?

 

On my Dell it doesn't matter which USB Port I use but I got a Special 6420 package from Jake Loo for my i5 System with Post #13.

 

Good luck...

 

Lars

Hello Lars,

 

i tried an other USB stick and tried it with also with "-v" but got same failures at booting.

Then i tried your Extra_I5 drivers and got:

 

EB OS read error: Controller or device error

Bock 0xacc08 Sector 0

 

:-(  :-(  :-(  :-(  :-(  :-(  :-(  :-(  :-(
