Sounds like standard use. > 2) We want start a Linux Kernel that is recorded (neither payload) after > LinuxBios binary in DoC (p.e.), then we execute linuxbiosmain() and in > the end of this function we make a long jump to 0x90000. Linuxbiosmain() is deprecated code and it always jumps to 0x100000 1MB. Anything is not done. And everyone is encouraged not to use linuxbiosmain for new deployments. > Here, i don't see what function in linuxbiosmain() copy the code of > Kernel to DRAM.Any one know it ? It is the gunzip part. But please don't use that. Eric _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
