Having a M4 SSD 256Gb with the older firmware I have problems that maybe once a week the computer freezes.
My Macbook Pro early 2008 with the latest OS X Mountain Lion don't have a working optical drive, so I can not follow the instructions creating a CD to startup and run the firmware update.
I have an external harddrive with the system working that I can startup the computer from. So now I wonder if and how I can start from the external disk, and run the upgrade from there?

The SSD firmware version is stored on the SSD itself so the upgrade does not need to be carried out on the system the SSD will be used in. The easiest way to upgrade the firmware is by connecting the SSD to a system that has a CD drive.
If this is not possible, you can follow these steps to create a bootable USB flash drive and upgrade the firmware from that.
1. Connect an empty USB flash drive
2. Download rEFIt-syslinux from the link below. This will allow your USB drive to be recognised as a startup volume by the mac.
3. Mount the dmg. This will mount two volumes called 'rEFIt' and 'SYSLINUX'
4. Open a Terminal and take a note of which volume is which with the command diskutil list:
e.g. /dev/disk1 for the USB drive and /dev/disk2 for the dmg
5. Unmount (NOT eject) both these volumes:
diskutil unmountDisk /dev/disk1
diskutil unmountDisk /dev/disk2
You should get a message saying you were successful
6. Copy the dmg onto the USB drive:
dd if=/dev/disk2 of=/dev/disk1 bs=1m
You should get a message detailing the number of records in and out and number of bytes transferred
7. Eject both:
diskutil eject /dev/disk1
diskutil eject /dev/disk2
8. Unplug and plug back in the USB drive and mount the SYSLINUX volume
9. Download the firmware version 0309 for the M4 SSD here:
10. Unzip and mount the firmware ISO and go into the folder BOOT, then ISOLINUX
11. Copy the contents into the SYSLINUX volume
12. Delete the existing file syslinux.cfg and rename ISOLINUX.CFG to syslinux.cfg
13. Reboot your mac and hold the option key to select a boot volume and select the eEFIt volume, then choose the "Boot legacy OS SYSLINUX' option
14. Follow the instructions to update the firmware.
Please let us know if we can offer additional assistance or advice.

This doesn't work on my MacBook Pro (2.4 GHz i7) with OSX 10.7.4 and it is well documented here on the forums that this will not work with all Mac's. We need a solution to this problem for those people who purchased an M4 and do not have an optical drive.
After selecting "Boot legacy OS SYSLINUX", the message I receive is:
"No bootable device--insert boot diskand press any key"

Nope..this doesnt work on a Macbook. It might on a windows machine, but not a MAC.
Crucial: any support on this? You guys supply directions for making a bootable USB device for windows, but nothing for MAC etc.

For the above link, under the Requirements it states:
- Microsoft Windows 2000/XP/Vista/7, or Linux, or Mac OS X 10.5+. Note that resulting USB drives are bootable only on PCs (not on Macs).

Anyone tried replacing ISOLINUX.BIN in the ISO with a more recent one?
download latest .zip
grab ISOLINUX.BIN in the \core folder and replace the one in the firmware ISO
I don't have a mac myself, so I can't test this
