hi all,
I am attempting to install centos 4.4 on an ebox 2300sx. I start with "i586 text" everything starts up and then I get: No coprocessor found and no math emulation present.
How do I get math emulation?
THanks
Jerry

You build a kernel with math emulation enabled.
Huh, cute machine. Too bad about the copro though.

I was wondering is there an older centos version that has emulation already built in? Which one ? I am not stuck on using 4
THanks,

CentOS 3 has only i586 and i686 kernels, those both rely on hardware FP
no, I think you'll need to build your own kernel RPMs for that one, or use a different sort of distro entirely. You'll need a i386 kernel, as that was the last CPU which had external/optional FP.

ISTR that you could enable FPU emulation on any arch, and it would be ignored if a FPU was present. Has this changed?

right, but standard kernels built for i686 or whatever are likely to ASSUME they have hardware FPU as every PentiumPro and newer CPU had this.
