bootforth seems to be working well enough for me and others to turn on by default. If it causes trouble, it's very easy to switch off again.

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.
