If anyone's ever had their hands on a IA-2, then they've surely though about hacking it.
This is suppose to be the CRT version of the Compaq IA-2.
You open it up to see real SDRAM for upgradability, a pair of jumpers SPECIFICALLY labeled "Erase BIOS"
A MiniPCI card, some models come with an ethernet port that has a sticker on it "Not For this VERSION" convering and most interesting of all a IDE port (which really IS an IDE port)
You boot it up and after a quick peak at the compaq logo it goes straight into booting up the Windows CE built into the 16Mb DiskOnChip 2000 built in.
Piece of cake right? Just flash the BIOS like the IA-1 and use the IDE to set up a computer for the kids for under $30.
But many have tried, and any hard disk you hook up (externally powered of course) of any size (tried 1G through 30Gb) all with boot versions of Linux and windows got only this:
"TrueFFS-BIOS --Version 3.3.7 for DiskOnChips 2000 (V1.23) Copyright (C) M-Systems, 1992-2000
INCORRECT BOOT DEVICE!!!!
PLEASE POWER OFF THE SYSTEM, REPLACE THE BOOT DEVICE THEN REBOOT THE SYSTEM"
with the BIG Compaq logo below.
"Erasing" the bios does not work. Holding the pins in the "ERASE BIOS" section doesn't work. Short circuiting does nothing. There is no way to get to the BIOS screen.
NOW FOR THE GOOD NEWS (SORT OF)
EURIKA! There is no need to get into the BIOS since if there is anything connected to the IDE port it tries (and fails so far) to boot from it. Ignoring the DiskOnChip.
No hard disk of what ever size, or of what ever boot partition worked, and always was the "INCORRECT BOOT DEVICE!!!! "
Until a not so tech guy like me got a hold of it and through what other "BOOT device" goes on the IDE.
It worked. (well kind of)
The IA-2 triest to look at the CDROM to see what's there and since it hasn't been able to find what it's looking for ignores it (No error messages) and then quietly boots of the DiskOnChip.
I think we've found a way to hack the IE-2, or at least get images onto the DiskOnChip without a Chip Programmer.
---- But Here is Where I Need YOUR Help -----
The IA-2 seems to be looking for something in the CD and doesn't find it and ignores it, but doesn't error out, so what is it looking for.
I tried windows XP, windows 98 installaction and even mandrake boot cd's.
But I'm thinking what the BIOS is looking for is a particular file name if it finds it hopefully upload it to the DiskOnChip.
My logic goes like this. They've built a quick way a tech store can format and rebuild, or upgrade the DiskOnChip image without having to have a ChipProgrammer.
Simply download the correctly named Image file, burn it on a cd, and plug the cd into the IA-2.
Any ideas what the name of this file is?
I've tried the file IE thinks is called "clientman"
http://webcdownload.msn.com/clientman/clientman.dll?Downloadimage?CurrentVersion=0&Component=Mariner;Compaq-2-2001;409&SSN=1 as innercore suggested, but I think IE thinks it's called clientman because of the dll that's needed to call it.
Any ideas. Anyone had experience with the Compaq Technical support telling you to download a particular file?
Anyone seen some files on HP or old compaq pages talking about help with the IA-2 other than the boring manuals they have here
Just starting a LONG (hopefully) discussions.
I just bought this for $70 (including shipping) on ebay and feel stupid for not researching more.
Hope you all get exicted with this piece of news and give me hints (which I promise to try) on what to do.
