Two years ago(?), working from an old tarball on a 430TX-based board, I threw the quoted C code in where the jump to the linux kernel normally goes, and apparently I modified the GDT as well. The experiment convinced us to go this route for our PIII BX board running a different RTOS instead of buying a BIOS solely for its SDRAM init, pci enumeration, & disk boot capabilities. If there is a cleaner switch to real mode available now, use it. (You can see that I was patching code in ram in order to jump to a 16-bit protected mode segment, and that the chipset wasn't entirely cooperating.) You might also look to see if there is a protected mode entry point to your vxWorks code. I don't know if that is feasible or not. We haven't done vxWorks for 2 years, and only a couple printed manuals were saved from the Great Purge. -- _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
