hpcboot.
“Ss Kernel” Ss Tab
On this tab you can select the kernel to boot and options to pass to the kernel.
-
-
- Directory
- In this combobox you specify the “current”
directory. The kernel and miniroot image pathnames are taken to be
relative to this directory.
hpcboot can load kernel and miniroot from FAT and UFS
filesystems, and via HTTP.
-
-
- Kernel
- In this text field you specify the name of the kernel to
load. Kernels compressed with
gzip(1) are supported.
-
-
- Model
- Select your H/PC model in this combobox.
-
-
- Root File System
- This group of controls lets you specify the desired root
file system type. You can select
wd(4),
sd(4),
md(4), and NFS root.
If you select md(4) memory disk
root file system, you should specify the path name of the file system
image in the text field below. Miniroot images compressed with
gzip(1) are supported.
-
-
- Kernel Boot Flags
- This group of controls is used to pass boot flags to the
kernel.
“Ss Option” Ss Tab
On this tab you can specify miscellaneous options that mostly control the
hpcboot program itself.

automatically boot NetBSD after the specified
timeout.

after the kernel has been loaded and prepared to be
started. This will be your last chance to cancel the boot.
-
-
- Extra Kernel Options

pass to the kernel.
“Ss Console” Ss Tab

“hooks” a developer might want to use during
hpcboot development.

BUGS
hpcboot reads the entire kernel image at once, and requires
enough free area on the main memory.
