Microcode question ?

[Riko Ho]

Everyone,

Is it ok if I'm not including microcode updates ?

Please see the capture...

I have done compiling for i946GZ, but not yet tested on the board....I 
have my spare flash chip only different type....on board is FB series, 
my spare chip is FC...

Cheers

Rick

It might, or might not. On the i945/946 it probably is ok. A lot of
modern CPUs can't boot successfully anymore without loading microcode.

Use native graphic initialization

Everyone,

I saw in make menuconfig

*Use native graphic initialization

How can I use it, so I can use my onboard VGA displaying message to LCD 
monitor ?

Cheers

Most modern ARM, MIPS, and AVR CPUs can.

ARM does not have the concept of microcode, except for possibly a couple
of derivatives (Tegra, ?)

Confusion I suspected is many many chips not x86, where microcode most 
relevant. In fact, with all little processor everywhere, x86 only little 
part, and not "most". I see you and Ron very effective at make this clear.

OK, then, although Stefan's meaning is pretty obvious, we can say it this
way: For those CPUs that have microcode, many can not boot successfully
without loading up to date microcode. For those CPUs that don't have
microcode, this question won't appear in the menuconfig.

Therefore, if you see this question, you have a CPU with microcode. In many
cases, if you say no, you may see troubles with your hardware. In some rare
cases the CPU can't even configure memory correctly.

I hope that's sufficiently clear?
