Hi and good morning, I am new to this coreboot thing. I would like to know what techniques people are using to avoid bricking their motherboard the first time they use coreboot (ie, at the point when a person is completely ignorant about what they are doing).
I've looked into the IOSS RD1-LPC8 Bios Savior but haven't been able to get a response from the company. I suspect that the product is no longer available. Too bad, that looked like it was exactly what I needed.
My motherboard is the H8DME-2 with an 8 MB LPC flash.
Regards, Joe

Hi,
I'm using extra flash chips and a second motherboard with the same socket to write them (Hotflashing). And to better handle the chips, I glued a pin head (without the needle, of course ;)) on top of them. http://www.coreboot.org/Developer_Manual/Tools

Find or buy a spare flash ROM (you could the one from another board and back it up so you can restor it when you are done). Turn on the system, pull out the original ROM and put it some where safe. Put in your spare and start flashing. If you ever brick it you can always put the original back in to start the system.
Mvh Anders

buy two flash roms. Make two copies of factory bios. Save one somewhere really really safe.
Because, sooner or later, you are going to forget and accidentally flash over the factory bios, and then you'll be sad.

Yes, very sad:) The double-backup approach is now in my plans.. Thanks, Joe
Just a hint, they don't have to be the same model or even brand.

But make sure that they are compatible. You mentioned that you have 8Mb LPC flash, so some candidates would be:
SST49LF080 Winbond W39V080A (NOTE! not 080FA, which is incompatible) PMC Pm49FL004T (yes, only 4 Mbit)
Nothing with Intel brand, they are all incompatible.

Thanks. The mb shipped with the SST49LF080A and I have found that exact part which I just ordered a handful of. Hope they come soon, I want to play with this!

Great! I hope the suffix matches too, I guess it would be -33-4C-NHE. Sorry, I should have mentioned that. But as long as it is PLCC, the suffix doesn't really matter.

Good lock :)

You can either buy empty flash chips of the same type and program them yourself or you can buy already programmed chips from many small shops or on ebay. (you should also buy such a removal tool) (just google a bit to find such a shop, probably also someone can suggest such a shop in the US)
For development there are LPI emulation devices, so you can save the time to program a chip for experimenting.
