Support, by way of the IBM/Microsoft int 0x13 extensions, was present in the new bootblocks a few months ago but was removed: too many BIOSes don't implement this stuff properly. Unless you patch the boot code youself, you must ensure that your kernel resides completely below cylinder 1024. Just sticking /boot/loader on a floppy is not going to help in the least. As regards the cylinder > 1023 issue, you can save yourself some time by regarding the above information as definitive. All the current booting tools (see src/sys/boot) do support both a.out and ELF. This applies both to the bootblocks (boot1 and boot2) and to /boot/loader. -- Robert Nordier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
