Excellent! :)
Thank a lot of people here. The mistake I made is building LinuxBIOS on a FC machine and testing it on another RH machine, many machine check panics arose.
The GNU toolchain (gcc and binutils) in the FC system may be unable to build LB correctly. Can you tell us what version of gcc and binutils you were using in the FC system that produced bad results, and what version you have used to produce a working result?
The one thing left is that keyboard is not enabled in Linux. It seems it is not correctly configured in LinuxBIOS. I have to use a serial port and terminal to access the machine. Where the keyboard is enabled in LinuxBIOS?
That depends on what the keyboard connects to. Is it a USB keyboard or a PS/2 keyboard? Whatever it is, could you also try the other? Also see Ron's question about which chip the keyboard is connected to.
And maybe easier, Linux has some kind of application like Windows to configure keyboard or not?
Not always an application, but there are configuration files in most if not all Linux distributions for setting up the keymap. That doesn't help if the kernel can't see the keyboard however. Feel free to send a serial port capture from a full boot with LB to the mailing list, we'll look at it and see if we can find something pointing to the error.
