Try backing up C, reformatting it, and reinstalling the dash and everything from an installer. I always use the OGXbox installer. I've never even used Hexen and I hate it. Lol.

Logically, the MS dash should have no problem being found by the MS Bios, but this is an extraordinary situation, really.

well I've done that and you are right OGXbox installer is great , way more options , but I got same results , i desoldered 4 wires that came form piggy back memories and I dont get error 16 , I dont know! all of my 8 rams are Samsung and I have checked connections , it appears that rams are making trouble ,I will check rams again to see if there is something I am missing.

You tested each RAM module separately with XBlast OS during the install?

yes sire , and although it passed the test ,due to freezing on boot, I find out that one of chips was loose and I have redone the soldering the freezing is gone but this is my new problem

Is the stock MS dashboard installed on the C drive?

 

Where's your replacement dashboard installed?  Does CerBIOS's settings file, Cerbios.ini, have a path set to it for one of the boot order list entries:

 

 

well first of all thanks for reply ,
replacement dashboard is installed on E:/Dash/main/Xbmc4gamers
I just flashed cerbios without using .ini file , I used cerbios utility and I specified the dash I want to boot first 
to keep things simple let say I want to remove modchip and get into stock ms dash , and yes ms dash is installed by hexen on drive c , when I remove modchip, I get Error 21, that isn't normal is it? and BTW the bios I used before upgrade was m8+ and it boots successfully randomly ,but as I said when I turn on console by eject button I get error 16 and I cant boot into dash no more for hours  , what would you do?

Hi friends!
as title says I get error 16 every time I boot with Cerbios , and i get that error with m8+ too when i turn on Xbox with eject tray ,everything were fine before I decided to give 128mb ram upgrade a shot on my 1.6 OGxbox , I have deleted and formatted all the partitions and installed everything from scratch still i am getting that error , I dont know that if it is hardware related or not please help me I am out of patience by trial and error

Sorry guys now that I look over my posts i don't know that here was the right place to post them ,but anyways one of memory chips wasn't 100% attach to memory beneath it ,my friend has done the first one to show me how to do but the other 3 were my own soldering I didn't suspect my friend's job but surprisingly not one but many of pins were not soldered correctly by my friend and there wasn't continuity between same pins , so I think that "Xblast os" thing is rubbish since it can't confirm if all pins are soldered correctly , after redoing soldering I get xbox to boot but it gives error 16 on Cerbios and it says something about clock I have no idea what it means but I think its not hardware related may be by reflashing another bios it will get fixed I don't know, if there is something to tell me about it to get it fixed tell me please , thank you guys you are awesome

Cerbios uses the same bios for all motherboard revisions, supports 128MB and has the ability to go up to UDMA-6.

The Cerbios pack.

UDMA-6 version, if you want it:

Hi friends, I have done 128mb ram upgrade on my 1.6 OG xbox , every chip I installed, I checked with Xblast os on Aladdin mod chip and it gave me success for all 4 banks but when i reflashed the modchip with m8plus1.6 either untouched or modified for 128mb ram or titan and etc , it just boots blackscreen, meaning that no frag or whatever, steady green light with hdd spinning but no picture at all ! I read somewhere there is a short somewhere but I'm confident that I don't have any shorts on circuit since there would be frag , any thought would be appreciated !
