While there are many users just like me, who had the problem that their drive wasn`t detected by the bios, I searched and found a solution.

The post is from Jack, evenso all the credits: http://www.jack-brennan.com/?p=1302, only the part about the bootable usb is by me.

I will quote the original post from him here.

This is a quick post to help users who are having trouble getting their Samsung F3 Spinpoint drives working with their P67 or SB850 chipsets. Symptoms of this problem might be:

• Clunky or loud drives
• Poor performance
• Drive not detected in BIOS

Official statement from Samsung:
This patch code is released in order to solve the compatibilty problem between some mainboard (AMD SB850 chipset and Intel P67/H67 chipset) and our HDD (F3 and F3EG model only).
This patch program works only to:

• F3     (HD323HJ / HD502HJ / HD503HI / HD103SJ / HD105SI)
• F3EG (HD153WI / HD203WI)

Start by downloading the boot CD (13.6MB): Download UBCD-Fix (MD5: c13a63798fc5237bfb48b3d49bec6d72 18.11.2011)

`Well I don`t have a cd burner in my pc, so I need to made a bootable usb from this download. See below how to do that, and how you can get your drive visable and working again.`

At first, download the program “unetbootin-windows-563” http://unetbootin.sourceforge.net/
Start the program, select diskimage, and next to that choose ISO, and next to that choose the UBCD-Fix that you just downloaded. Select the USB-station (Location where your usb drive is). When this is ready, you have a nice working booting usb stick with the firmware on it.


How to:

1. Restart your PC and boot from the CD (You may have to change the boot order in your bios)’
2. At the boot menu select UBCD FreeDOS R1.37 (Based on NwDsk V3.40).
3. Another menu might pop up, just select the first option.
4. You will then come to a screen that looks like this: Please take notice of the CDDRV drive letter. Mine is T.

5. In the menu select Browse or just press B.
6. You will then be greeted with the following screen. Change to your CD drive by typing X: and press enter. Where X= your cd drive letter; which we found out in step number (T:) 

7. Now type DIR and press enter. You will see a list of  files and directories. You should take notice of the Fix directory
8. Type cd fix (yes there is a space there).
9. Notice: Please double check your model number and apply the correct firmware update:

        F3.exe = (HD323HJ / HD502HJ / HD503HI / HD103SJ / HD105SI)     

        F3eg.exe = (HD153WI / HD203WI)

10. Type F3.exe or F3eg.exe to run the correct firmware update for your drive.
11. Once the firmware is update is completed turn your system off. Apparently if you only restart the flash might fail.

Notice 1:
If your firmware version is – 1AJ10001 this update is not needed as this firmware is unaffected by the SB850/P67 SATA bug. If you attempt to flash your drive you will recieve a similar error to this:
X: \> asus.exe
 
V 5:32 sFLASH Samsung Electronics Co., Ltd.. (C) 2000-2009
>> X: \ ASUS.EXE @ 02:27
[10 DEh/0054h] B = F = 0 D = 07h 00h C = 0S70 CTRL: 0x0B72 INT_LN: 11
{0} [SAMSUNG HD103SJ (1AJ10001 )]… NVIDIA SATA 0054 CH: 1 DEV: 0
This program is not available for this drive.

Notice 2:
Just a quick note for those guys that have problems with recognizing HD103SJ in BIOS : disconnect the SATA cable and power on the machine until the disk is fully up (about 11 seconds) .Then reconnect SATA cable and do the reset .
Now your drive should be visible in BIOS and flashing of the drive might be possible !
