the challenge is providing a BIOS equivalent to the bootable CD/DVD which allows access to hardware.
The solution OWC and others provides is to dismiss the GUI and get a Terminal window, then enter:
running as essentially Root, although a little risky if you screw up, gives you the needed Hardware access.

has anyone tried using the Mac ISO posted here?
yes i attempted it for many hours but could get no success.
Could you get the iso image to mount??
The ISO contains btdisk.img, isolinux.cfg, isolinux.bin, memdisk.
btdsk.img isolinux.bin isolinux.cfg memdisk
# FreeDOS OEM bootdisk, 360KB zip compressed
# overloading is a nice thing. Specify FreeDOS, and if another one is present

# cancel and try next boot device
btdsk.img: x86 boot sector, FREE-DOS Beta 0.9 Bootloader KERNEL.SYS, code offset 0x3c, OEM-ID "FreeDOS ", sectors/cluster 2, root entries 240, sectors 5760 (volumes <=32 MB) , sectors/FAT 9, serial number 0xc04d1342, label: " ", FAT (12 bit)
The problem is that btdisk.img kernel is the FreeDOS kernel which has no CMS-BIOS to support that KERNEL.SYS file hence no firmware update.
Testing gives and error that Samsung support engineers say is expected. It will either give 'NO EDD-BIOS' or KERNEL.SYS not found.
The OWC BIOS contains a modified version of DOS which is different.
How exactly did you burn the bootable ISO? I tried several ways yesterday (Toast and Disk Utility) and was not successful.
The image you download Samsung......DXM04B0Q_Mac.iso has an image file called BTDSK.IMG on it.
Did you burn the Samsung....iso image or the BTDSK one? I have tried both. With the Samsung image it was not visible to boot from at startup. With the BTDSK one it was available to boot but did not have the software.
Thanks for any guidance.
it was fairly straightforward. Let me start with what I used:
Samsung 840 (not the Pro) 500GB SSD
iMac 24" Early 2008 running 10.8.3 (at the time)
700MB CD-R media
I downloaded the file called: Samsung_SSD_840_DXT07B0Q_Mac.iso (no need to mount it)
dragged it into the left-most pane in the disk utility app, made sure it was highlighted and then clicked on burn.
During reboot, I simply held down the option key and the CD-R showed up as a bootable option. It boots into DOS and I really just followed these instructions verbatim:
Thanks for the detailed instructions. It is similar to what I tried but I will have another go when I get home tonight and will let you know how I get on. Let's hope the file I need for the PRO behaves the same way.
Did you do the update before you put anything on the SSD? Do you know if it affects the disc content?
Well sadly I have not been able to make a bootable CD or get a CD to boot windows. I used Disk utility to create it (although I could not drag the file to the left hand pane, I had to select it in Burn) and when I rebooted with the option key held down, then the CD was available as an option. However, when I selected it then the computer just hung. I thought that it might be that the file I have is not working as you had a different one. Thus I also tried the Samsung_SSD_840_DXT07B0Q_Mac.iso file to remove a variable but this was not bootable either.
I'm running a MacPro 2008 (3.1)
The only good thing is that looking at the SSD the firmware it shows is DXM05B0Q vs the DXM04B0Q updater so it looks as if I have a newer firmware anyway.
It is very frustrating though and shows that perhaps Samsung is not very supportive of Apple applications!
Thanks for your suggestions.
