Openbsd usb windows

OpenBSD's gratuitous logging and swap utilization killed that USB stick in a matter of months after daily use, but the thought hit me to use that same method here. By default, the bsd. This is an initial ramdisk, a bare-bones userland with just enough tools to install or rescue a system. So that's what we're going to do. If it's a 4GB stick or larger, the default partitioning scheme will work great. Otherwise, make one root partition without swap. Install only the base, bsd, bsd.

After install, re-mount the cd and copy the install files to the root partition. Shut down the system. The USB stick will now boot on most servers and netbooks lacking optical drives, and will go directly to the installer.

Here's the walk-through. I booted up the system, and after the installer menu popped up, I plugged in my USB stick. I did this to make it obvious what its device id is. You can tell it's sd0 in this image. This is the simplest way, although perhaps not the most efficient as you have to write MB of zeros! Copy the installer. Make it bootable! Host OpenBSD 5. You are now a ninja USB image creator. How to do something like this under OpenBSD?

That's a future story. Comments are closed. This is a control endpoint at address 0 and is used to give commands to the device and extract basic data, such as descriptors, from the device. Each endpoint, except the control endpoint, is unidirectional. The endpoints in a device are grouped into interfaces.

An interface is a logical unit within a device; e. An interface can sometimes be set into different modes, called alternate settings, which affects how it operates. Different alternate settings can have different endpoints within it. A device may operate in different configurations. Depending on the configuration the device may present different sets of endpoints and interfaces. Each device located on a hub has several config 8 locators:. The first locator can be used to pin down a particular device according to its physical position in the device tree.
