content: I wanted to ask and see if the EEVblog community had any insight on this. I am working with 64 computers at a time and need to boot them all up and configure the bios. What I am looking for is a thumb drive that I can replicate 64 times that can either spam the F2 key or actually configure the bios by programming in the correct key strokes in. I have also looked into modding a keyboard but I don't want to do that 64 times. Please let me know if anyone has has any experience with this sort of idea. I am pretty open to try any solution.

content: He wants 64 of them... a bit expensive, those things. A low-capacity flash drive with a hackable MCU (usually 8051-based) might be ideal, if reverse-engineering isn't hard for you.

content: Why all the computers need to be booted up at the same time? How about doing 5-10 at a time?https://hakshop.myshopify.com/collections/usb-rubber-ducky/products/usb-rubber-ducky-red-team-10-pack10 pcs for 300$, or 10 pcs teensy 3.0 190$ total, I'm sure they could get some kind of volume discount. If this is work and it produces money that shouldn't be too much?Dave has few videos about him doing testing of µcurrents, he also breaks them up into manageable chunks since doing 50 or 100 at a time might be just too much.

content: If you are planning for a DIY solution, an Attiny45 (might even work down to an Attiny25), two resistors and two 3.6V zeners is enough to create a HID keyboard emulator. A colleague lost the function of the DEL key on his MacBook and got a single-key keyboard based on the above from me.I guess the only difficulty is the exact timing, when to send the F2 after power-on.On the other hand: all BIOSes which I have seen since the middle 1990's have an option to bypass thekeyboard checkpermanently. This would mean that you would have to do it for all 100 computers once, but still this seems to be the cheapest and fastest solution to me...Some links:http://blog.flipwork.nl/?x=entry:entry081009-142605;comments:1http://macetech.com/blog/?q=node/46http://www.obdev.at/products/vusb/index.html

content: Thank you all for your contribution. We have since discovered that these nodes in the computer can have the bios cloned through the whole array. That part of the system was not explained to us when we started. Ask and you shall receive. I think I still will be using the ducky for my own personal projects in the refuter though. awesome suggestions guys. thanks a million.
