# $FreeBSD$
This is the new unified bootstrap, sometimes known previously as the 'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.
1998-08-21 03:17:42 +00:00
Initial integration of the i386 bootloader and BTX. - Discard large amounts of BIOS-related code in favour of the more compact BTX vm86 interface. - Build the loader module as ELF, although the resulting object is a.out, make gensetdefs 32/64-bit sensitive and use a single copy of it. - Throw away installboot, as it's no longer required. - Use direct bcopy operations in the i386_copy module, as BTX maps the first 16M of memory. Check operations against the detected size of actual memory.

BASE= loader
Add the new cdldr CD bootstrap loader. This patch includes the following: - Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel arguments. - Add the cdldr bootstrap program. This program is tacked onto the beginning of the standard 3rd stage boot loader (/boot/loader) to form the CD boot loader (/boot/cdboot). When a CD is booted, the cdboot file is copied into memory instead and executed. The cdldr stub emulates the environment normally provided by boot2 and then starts the loader. This booting method does not emulate a floppy drive, but boots directly off of the CD. This should fix the problems some BIOS's have with emulating a 2.88 MB floppy image. - Add support to the loader to recognize that it has been booted by cdldr instead of boot2 and use a simpler method of extracting the BIOS boot device.

- Enable PnP and ISA PnP code. - Use the ISA PnP enumerator. - Use the new linker set code, throw out the gensetdefs stuff. - Produce an intermediate loader image that has symbols stripped, to aid - in debugging. - Supply ISA port access functions required for ISA PnP

This is the new unified bootstrap, sometimes known previously as the 'three-stage' bootstrap. There are a number of caveats with the code in its current state: - The i386 bootstrap only supports booting from a floppy. - The kernel and kld do not yet know how to deal with the extended information and module summary passed in. - PnP-based autodetection and demand loading of modules is not implemented. - i386 ELF kernel loading is not ready yet. - The i386 bootstrap is loaded via an ugly blockmap. On the alpha, both net- and disk-booting (SRM console machines only) is supported. No blockmaps are used by this code. Obtained from: Parts from the NetBSD/i386 standalone bootstrap.

Try and get the sys/* and machine/* includes via relative paths. This saves having to do a 'make includes' after touching any header file for the boot code.

Initial integration of the i386 bootloader and BTX. - Discard large amounts of BIOS-related code in favour of the more compact BTX vm86 interface. - Build the loader module as ELF, although the resulting object is a.out, make gensetdefs 32/64-bit sensitive and use a single copy of it. - Throw away installboot, as it's no longer required. - Use direct bcopy operations in the i386_copy module, as BTX maps the first 16M of memory. Check operations against the detected size of actual memory.
