See https://wiki.gentoo.org/wiki/Project:Distribution_Kernel#Using_.2Fetc.2Fkernel.2Fconfig.d

Option is CONFIG_M486SX=y (without FPU) or CONFIG_M486=y (with FPU)

thanks. I see this and know howto build all by hand. I want to know why the platform I am using is i486,486 compile chain, I think the base root is 486 ready, but the dist kernel is i686ready and need to adjust my self.

if I run gentoo with amd k6-2, pentium mmx cpu before pemtum pro pentium2 , I still need I486 platform?

youxiaojie,

The pre pentiumpro CPUs you list are all i586.
They all have an FPU and will run 586 code.
