But please don't use that. The problem, is that, if i follow the instructions of freebios/HOWTO/SiS630, the linux kernel binary generated doesn't has elfheader. Then if i want to use the standard use, i have apply some external utility to generate an elf file (mkelfImage) and put in config file "fileoption USE_ELF_BOOT=1". Is it right ? Another think, i thought that the Linux Kernel alone has the code to decompress himself (in the same way that we can put Kernel in a floppy disk and it decompress alone. (dd if=kernel of=/dev/fd0)) Thanks. Xavi. _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
