unable to perform BIOS recovery / M92p tiny

2018-02-15, 23:37 PM

Hi ...

i am having hard times to update / recover the bios of a number of machines which i own.

within my basement i have around 20 m92/3p machines running - and i was able to handle/update them in the past quite well with no issues so far.

machine type => M92p Tiny 3227 / running linux normally

What i tried so far:

+ Bios recovery with image versions x79 / x98 / x99

+ recovery through USB memory or with the standard CD/DVD-Drive

+ CMOS battery existing one, removed or a new one

+ recovery jumper on 1-2 or 2-3

 

in general the system does not have any video output any more on the internal VGA - after a while it goes into dual beep-mode and stays there

however - during the recovery procedure of the BIOS, it shows the bios update screen until it goes up 100% and says COMPLETE - then the machine turns off (like described within the HMM)

but afterwards it falls back into darkness :-(

 

i alredy tried to update a second one, which failed too unfortunately - i don't know what i am doing wrong

this time i stayed with the machine to follow the update process - i went stuck at 1% and never went any further :-(

 

any new ideas are more then welcome

If you run an update on a working computer and it doesn't work after the update I'd say the problem might be related to incorrect version of BIOS.
Can you share the site you obtained the BIOS from?
On a side note- why were you updating the BIOS in the first place?

Hi ...

i intended to update those boxes because i had problem with the usb-ports under linux.

i wanted to connect 4 usb-ethernet-dongles - they work if you plug them in until a reboot happens, then you loose one or two.

however ... all bios-images i tired came from the lenovo site

https://download.lenovo.com/pccbbs/thinkcentre_bios/9sj998usa.iso

https://download.lenovo.com/pccbbs/thinkcentre_bios/9sj999usa.iso

 

i am wondering what am i doing wrong so non of those recovery attempts have success?

the flash-process starts and by magic i also do have a video-output during this session.

but afterwards, it falls into darkness again

I know it's not an answer to your question, but maybe you're going wrong way about it?
Did you try to restart the network service or individual ethernet adapter after bootup?

yeah ... tried that, but most of the time the usb-devices were totally lost - so no device visible any more under linux.

even tried to restart the complete USB-Bus with no effect.

i also own a couple of m93p tinys - and will do the same tests with those boxes to see if they do any better

what happened in the meanwhile ....

i played around with those two machines i lost for another two evenings.

 

it seems like flashing it through the recovery mechanism in genereal works - because sometimes (haven't figured out what the trigger for this is) i hear two loud beeps from a regular boot and i see a POST message from american megatrends plus an error 0175 - security data corrupted ...

if i then enter the BIOS i can check the version which changes - whatever version i recovered when the jumber was on position 2-3.

so looks like the problem is not that i cannot flash a bios, it is more like the one i put on does not get written in the right way.

i cannot even say how i manage to get to this situation that i am able to see this AMI screen ... from my personal impression, there is a relationship to the fact if i pull the CMOS battery or even run without it

You may be experiencing a slightly different issue then me (not sure if you used hardware passwords before the update?) but for me the problem was a delaminating BIOS chip. Remove HDD, and do the recovery whilst pushing -firmly- on the ITE labelled '100 leg' surface mount chip that is mostly covered up by the HDD caddy. In my case the update this way went right up to 100%, machine turned off, jumper back, worked perfect after.  Of course this means the motherboard can die any time from solder faults. So... if this gets your PC booting, you might want to stop using it for anything mission-critical.
