Contents of README:$NetBSD: README,v 1.3 2020/08/16 07:25:51 isaki Exp $ Primary bootloaders: boot_ufs/ contains xxboot_ufs. It is placed in ffs's boot area and loads secondary bootloader from its filesystem (ffsv1/v2). This historical primary bootloader uses custom ffs op functions. xxboot/ contains following variants. * cdboot_cd9660 is placed in CD and loads secondary bootloader from cd9660 filesystem. * fdboot_ustarfs is placed in floppy's sector#0 and loads secondary bootloader from subsequent USTARFS. * xxboot_ffsv1 * xxboot_ffsv2 * xxboot_lfsv1 * xxboot_lfsv2 is placed in each specified filesystem's boot area, and loads secondary bootloader from its filesystem. These primary bootloaders use MI ffs/lfs op functions in src/sys/lib/libsa. Secondary bootloaders: boot/ boot is placed to / (root directory) and loads the kernel. netboot/ netboot is the same as /boot except default boot device is nfs using network interface and DHCP. Currently only NE2000 based Neptune-X and Nereid are supported. Other bootloaders: mboot/ mboot is 0-th bootloader. It is placed to sector#0 (as 1024byte/sector) of hard disk as an alternative to genuine boot selector. And loads active partition's +0 sector (sector size depends media) which should have primary bootloader. loadbsd/ loadbsd.x is a Human68k executable and loads the kernel from Human68k filesystem. Utility tools: newdisk/ newdisk is a utility to create the "disk mark" for X680x0 SCSI IPL using mboot bootloader to make a disk bootable. |
