* The boot loader does now set up an IDT that allows it to catch processor exceptions (page faults and the like). The handler dumps possibly interesting information (registers, a (numerical) stack trace) to the serial output, and, if possible, also to the screen. That should help debugging boot loader crashes. * For the IDT the boot loader sets up for the kernel the descriptors are set up the same way, so until the kernel initializes the IDT itself (arch_init()) the facility is still in place and can thus catch very early kernel boot crashes. Unfortunately the on-screen output doesn't seem to work anymore at that point, so the output only goes to the serial port... * ... and to the debug syslog -- dprintf() does now append it there after debug_cleanup() has been called. Seems to work fine in qemu, but when I tested it on real hardware the debug syslog was gone. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42092 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add MultiBoot support. Based on a patch from Dustin Howett, reworked, and help from Vladimir 'phcoder' Serbinenko. - used defines for clarity, the rest of teh code could make use of them too... - added a gMultiBootInfo pointer to the passed args, to let C code handle it instead of faking the boot drive ID, - conditionalized the copy back, maybe we can get rid of it when QEMU handles our default load address correctly, - added video mode info to ask for 1024x768 but QEMU ignores it anyway, and we might need to show the menu, so it's disabled. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32059 a95241bf-73f2-0310-859d-f6bbb57e9c96

Removed platform_boot_device_is_image() - platform_get_boot_device() now fills in the adequate field in the kernel_args structure. Renamed gCDFloppyBoot variable to gBootedFromImage (as network boot should look similar). The "kernel_args.boot_disk.cd" field is now maintained as well. The print_item_at() menu function now prints the Menu::ChoiceText() instead of that of its marked item. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14389 a95241bf-73f2-0310-859d-f6bbb57e9c96

The boot loader now has special support for being booted from a boot image like floppy or CD boot. This allows it to reduce the number of scans needed to identify the boot partition - when booted from a real floppy, this speeds up the boot process by a magnitude. Also, the loader now has a fall back in case there were no "boot" links on the disk - the current boot floppy script doesn't create them. With these changes, I was able to boot into a HD based Haiku installation from a floppy disk. It's not yet enough to boot from CD (as the boot device selection is a bit too simplistic right now), but it will eventually come next. Testing is a lot slower here, though, as neither qemu nor Bochs support multi-session CDs (at least I have no idea how to get them to do this). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14380 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now loads the maximum size of zbeos when booted from a floppy or CD. Note, this value should be patched by the build system to the actual size of zbeos - but since we don't have this mechanism in place yet, the maximum value is probably the best default, even if it should slow down a floppy boot considerably. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14344 a95241bf-73f2-0310-859d-f6bbb57e9c96
