Thanks a lot for your help!!!! U-boot is now runing on my custom Pentium 2 board now, but the Linux Kernel still can not boot yet.
I compiled a bzImage , download to u-boot, it halt after print: Start Kernel....
this is the problem of my Linux Kernel ? or my u-boot still has problem? or both?????
The obvius question is: have you configured serial console correctly in linux?
It cold also be a problem with the load address you use, not all values will work,
I use 0x100000 wich works for me.
You culd try to figure out what the cpu is doing, if you have access to a hardware-
debugger of some kind.

No.
You could try to issue the following command at the u-boot prompt before typing bootm:
setenv bootargs console=ttyS0,9600
Also verify thet you haveCONFIG_SERIAL=yCONFIG_SERIAL_CONSOLE=y
In your linux kernel .config file.
