Hi, I'm thinking perhaps we can make it more generic and support multiple INT in one function. One way to do this is not use INT, but retrieve the address from IVT and do a far call. On return, pop the flag on stack. This would also make it easily to support far call, In that case, we just don't pop the flag. I also notice that you do the protected/real mode switch in grub_bioscall_int10h, why not use the prot_to_real and real_to_prot ? If you need to keep the value of %eax, you can store it in a structure and pass it using other register like %ecx. -- Bean _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
