.Dd December 23, 2023 .Dt LOADBSD 8 x68k .Os .Sh NAME .Nm loadbsd .Nd load and boot NetBSD/x68k kernel from Human68k .Sh SYNOPSIS .Nm loadbsd.x .Op Fl hvV .Op Fl abDNqs .Op Fl r Ar root_device .Ar kernel_file .Sh DESCRIPTION .Nm is a program runs on Human68k. It loads and executes the specified .Nx Ns Tn /x68k kernel.
p The options (for .Nm itself) are as follows: l -tag -width flag t Fl h Show help and exit. t Fl N Do not execute the kernel, if specified in combination with boot options. t Fl v Enable verbose mode. t Fl V Print version of .Nm and exit. .El
p The options for .Nx kernel are as follows: l -tag -width flag t Fl a Auto (multi-user) boot. This disables .Fl s flag. t Fl b Ask boot device during boot. Pass .Dv RB_ASKNAME boot flag to the kernel. t Fl D Enter kernel debugger. Pass .Dv RB_KDB boot flag to the kernel. t Fl r Ar root_device Specify boot device, which shall be mounted as root device. The default device is .Sq Li sd@0,0:a . Note that the boot device name is .Em not the same as that of .Nx . See .Sx BOOT DEVICE NAMES below. t Fl q Boot the system in quiet mode. Pass .Dv AB_QUIET boot flag to the kernel. t Fl s Single user boot. Pass .Dv RB_SINGLE boot flag to the kernel. This disables .Fl a flag. This flag is set by default. .El
p Although listed separately, the options may be in any order. .Sh BOOT DEVICE NAMES The format of boot device names is:
p .Dl "[/interface/]dev@unit[,lun][:partition]"
p l -tag -width Fl t interface SCSI interface type. One of: .Sq Li spc@0 , .Sq Li spc@1 , .Sq Li mha@0 . If the dev is a SCSI device, and interface is omitted, the current boot interface is used. t dev Device type. One of: .Sq Li fd (floppy disk drive), .Sq Li sd (SCSI disk), .Sq Li cd (SCSI CD-ROM), .Sq Li md (Memory disk). t unit Device unit #. You must specify the target SCSI ID if dev is a SCSI device. t lun SCSI LUN #. 0 is assumed if omitted. t partition Partition letter of device. Partition .Sq Li a is used if omitted. .El .Sh FILES l -tag -width /usr/mdec/loadbsd.xxxx -compact t Pa /usr/mdec/loadbsd.x You will find this program here. .El .Sh SEE ALSO .Xr reboot 2 , .Xr x68k/boot 8 .Sh HISTORY The .Nm utility first appeared in .Nx 1.4 . .Sh BUGS .Nm reads the entire kernel image at once, and requires enough free area on the main memory.
