Looking for V2 I-Opener image with qnxflash 1.02. Anyone?
Looking for files to hack I-Opener

Hello everyone! I am trying to hack an old v3 I-Opener. I can boot it from hard disk
using the BIOS from a v1 I-Opener. I would like to re-write the flash with a v2 QNX
including qnxflash 1.02 so that I can get the v3 BIOS to boot the disk.

Can anyone give me access to the necessary image file? The freedrive.com account
is long extinct.

Alternatively, I have a v2 image with qnxflash 1.0. How can I replace the version
of qnxflash with a newer one. Can some sort of loopback mount be performed under
Linux?

Thanks!

-Todd

Um. If you can boot of a hard-drive, then why not just grab a copy of the Award Flash tool (easy to find via Google) and flash it under DOS or Win9x MS-DOS Mode?

Hacking up the QNX stuff is a long-lost art, now that we've got BadFlash supplying easy upgrade kits. I could see why you'd want to do this if you still had a "gooped" machine.. but since you've already got it running the V1 chip, it seems like taking the *really* long way around (or historic/nostalgic way :o) to get the chip flashed.

Hacking the Sandisk image is cumbersome. Linux's QNX disk support isn't up to par -- mounting and reading it via loopback is fine, but writing the image caused corruption. The last time I tried, I was using RedHat 8. In the end, I just used the "root" backdoor to log into the Sandisk image, and doing the "modem-to-modem" hack to get a 56K ppp connection to my main workstation. Once that was done, I just telnetted into the machine.

Hacking the v3 via Sandisk image is even more cumbersome, because you have to prepare a hard-disk image with a v2 Sandisk image (needed for the root backdoor -- v3 closed up all the holes).. and then trick the v3 into booting that image by adjusting the BIOS boot settings. There are lots of articles in the Tech Moderated section on how to do this, if you really wanna go that path...

I tried that but can't find a version of the Award flash that works for me. I get, flash not recognized, or similar error.

It could be that the flash utility is too new or too old and doesn't support the chipset the IOP has.

Find an old socket7 motherboard that uses the same chipset as the IOP and use the flash utility that the company recommends for it. If you are getting an "unknown flashtype" error the flash utility is too old and does not know about the SST39SF020 bios chip.

>I can boot it from hard disk using the BIOS from a v1 I-Opener.

OK, you can then load that hard disk with just about any combination of DOS and Linux partitions with all the tools you could possibly need - say awdflash, fdisk, fips, dolly, ghost, drive image, partition magic, etc.

>I would like to re-write the flash with a v2 QNX including qnxflash 1.02 so that I can get the v3 BIOS to boot the disk.

You would like to rewrite the *Sandisk* image. This just requires standard utilities like fdisk, dolly, dd, and so on, not awdflash, which is used to flash the *BIOS*.

As has been pointed out, this is a really roundabout route to get a hacked IO. If you're careful, you can simply hot-flash the v3 BIOS chip that you have with a v1 BIOS image by booting into DOS with the v1 BIOS, hot-swapping it out with the v3 BIOS ROM, and flashing the v3 into a v1 with awdflash.

This requires extreme care to ensure that you don't end with a dead IO and two dead BIOS chips.

After that, you can upgrade to v5pmi or whatever the latest and greatest BIOS version is, without any risk.

The latest version of UNIFLASH flashes I-OPENERS just fine.
