Looking for advice
Problem with BIOS chip

New MessageLooking for advice (modified 0 times) comausa

Just started with my first IO project and need some advice. Successfully removed the epoxy from the BIOS chip, but now for some reason unit doesn't boot anymore. I don't think that I have damaged anything. Followed recommendations on this forum and did bend BIOS chip legs slightly outward, also tried with BIOS chip in various positions inside the socket, but no difference. Can switch power on with the power button and power led lights up, but nothing happens from there (CPU gets warm though). Strangely, it's not possible to switch the unit off (led still on) with the power button - have to unplug the power supply. Is it possible, that I have damaged the BIOS chip in the process of removing the glue? Or can you think of any other reason why the unit does not boot?

Any advice highly appreciated.

Thanks much in advance

Welcome to the wonderful world of the i-opener.

It causes its owner to wonder or gives its owner wonders.

Sonetimes an i-o will play dead.

The Bios should fit in the socket only one way. With the angled off corner toward the USB connector.

Two things to try:

1. plug in the wall transformer and push and hold down the power button until the led goes off. then power up normally.

2. plug in the wall transformer. push the power button to turn on the i-o. then push the reset button (located above the printer cable connector). then the i-o should power up without touching the power button again.

one of those should bring the i-o back alive unless you really did ruin the bios chip.

unless you want the i-o to be original (if so, why take out the bios chip?), you should get a replacement bios chip from Badflash. He also has replacement bios sockets.

have fun,

Also, I (and others) have run into the problem that after the goop removal process, the contacts are not great between the bios chip and the socket. On my first I-Opener, I had to carefully bend each pin on the chip out a little and make sure the contacts were very clean on both sides before it would boot. This took several attempts and I thought I'd lost the poor bugger, but it eventually booted.
