...6 mode, or on non-86 architectures run a x86 emulator if need be. You can't call the VBIOS from a device driver becuase it has been written assuming that it will be run in real mode, not protected mode. I tried linking to klibc but I'm missing some key pieces. I need things like inb/w/l(), outb/w/l(), iopl(), and vm86 support. Is it possible to get these added to klibc? These are probably all macros simply generating ASM instructions or calling the kernel VM86 entry point. ===== Jon Smirl jonsmirl@yahoo.com __________________________________ Do you Yahoo!? Yahoo!

Hi, These patches contain support for some features that are already in Syslinux 4 but weren't working properly on the elflink branch. It's another step closer to feature parity with Syslinux 4. Having to jump through the comboot API for localboot support is less than ideal and I'll eventually fix that, probably when we move a big chunk of code from asm to C. Also, there's a

Hi guys, At a loss trying to figure why if (has_eflag(X86_EFLAGS_ID)) returns false in my HVM domU. Standard function has_eflag() in cpucheck.c running in real mode. Works fine on PV dom0, but fails when guest is booting on my hybrid dom0. LMK if any ideas. I''ll keep digging in the manuals, but nothing so far. thanks, Mukesh
