This is no request thread! HP COMPAQ bioses, how to modify the bios?

Emergency BIOS Recovery

1/ Grab the bios file from www.hp.com.
2/ Copy the bios file to the floppy disk. If it's Rom.bin it needs to be renamed to the series of your system. Eg: 68DDU.BIN
3/ Switch on system and hit either the Win+B or four-arrows on bootup,
4/ Num-lock LED will start flashing and if you have the USB floppy attached it will start reading the file. If it stops reading the file after a few secs then there is something wrong with the file and/or naming.

It is possible to put a similar system's (X3100, ICH8M) bios on your system. eg: 6710b on 6910p. Though if the keyboard controllers are different then it remaps the keys making it harder to hit Win+B or four arrows. Consider holding down as many keys as possible on the keyboard if needing to again do a recovery.

Latest 6710b bios has newer 1585 X3100 vidoe bios. How to grab that an insert it into other systems using vbios 1471?

If can figure out where the bios stores parameters (NVRAM?) can then just modify the NVRAM to alter hidden bios parameters.

6710B bios has the SATA Native enabled/disabled option.

It was a couple of days ago when I was reading here last time....

I need a short update.

-override state , nobody is able to set it to enable, right?

-official biosupdate from SLIC2.0 to SLIC 2.1? An example found, I guess no?

The future of bioses: (to hide special tools from the public..only effective protection.....)

What about that odd uniflash? Is it compatible?

What I still don't get: Why are there still 2 SLICs inside the bios? One at the protected area would be enough....
At other Phoenix bioses I've found similar matter. There is written a SLIC Marker onto the chip using special tools (LENOVO). The biosupdate itself doesn't contain the SLIC marker...anyway, we can mod them, since we are able to decompose and rebuild the modules.......

Thanks...

Cause the bios needs to be flashed twice, i dont know why but i made my own experiment replacing repetitive strings whit FFFFF, result, boot but send that error message, maybe it make some kind of check i don´t know really, anyway i try the vpro command and doesn't work on my 6710b, so is there any other test-alternative to check?

[sebus]

I am sure vpro has nothing to do with anything, as it is related to Intel processor and ie 6715b which is AMD based has the same double slic BIOS that can not be "updated" to 2.1 in any way

6715b does NOT have vpro, hence my statement

sebus

Finally found a old post with tools and info that the DMI could be mirrored on HDD.....anything useful?

I have HP dx2280 mt
any idea how to update the bios to slic 2.1

Hi, Yen!
What do you think about it.
Is this a serious problem, or not?

P.S.
I've tried UniflashRE ver. 1.47re build 08 -> it's not compatible...
Something interesting can be found here, but

SPEG is a standalone programer,
it wont be executed on that machine so is not bound to any limitations.

ATMEL protection is nothing like that you saw in those messages.
In fact the flash has a sector by sector protection that
can be disabled one by one or globaly.

As I said, my software is able to read/write/unlock/erase
any ATMEL serial flash. The chip must be taken off from
the board and programmed using an interface and the SPEG program.

so, it's the same solution as was described here...

What about that odd uniflash? Is it compatible?

Has anyone tested uniflash and flashrom (Linux). Flashrom lists the AT25DF321 as supported using SPI interface.

Is there a guide on how to mod Phoenix bios?

[engage16]

Its fairly simple to mod a Pheonix bios with only one SLIC marker, but the majority of the new bioses have a second occurence of a SLIC and for some reason it seems to be hardware locked...
