The board comes with a ITE IT8716F 4MB chip; but that is compatible with SST49LF040A chips. I already have these and some SST49LF080A chips; just wish there were 160 or 320MBI'm hoping that's a typo, SST49LF080 is 8Mb (that's 8 megabits, or 1 megabyte), larger chips would be 16 or 32Mb (2 or 4MB).
Well if 040 is 4MB and 080 is 8MB, I would hope there is a 160 at 16MB and so on; or do engineers use a secret numbering system :-)
I used to do boot CDs pretending to be 2.8Mb floppies, and would be happy with a 4Mb chip to get a Linux kernel into.
How many do you have? You can use an SST49LF080 as a backup chip for the stock bios, just cat the stock bios onto itself to get two copies of it back to back, and then flash it onto the chip.
Yes, I will duplicate the factory BIOS, got about 6 chips. The BIOS does not have an option to write to a floppy; but flashrom works fine
Let us know how it goes! You will probably need to do some work on the IRQ tables before Linux will boot, but who knows ;)
Thanks I will, setting up a clean Linux development system right now, I like Linux from Scratch. How I hate distros that load in an hour; but it takes a week to find the header files.
Just for completeness I add the lspci -v. Once I have a stable system, and have duplicated the factory BIOS, I can start properly.
