You are using an out of date browser. There's always something I forget when I'm in the process of switching things around, and mixing and matching GPT aware and unaware systems. Haiku-OS on a stick is as fast as can be, especially for net browsing.
One of these days, I'll completely dispense with hard drives altogether, and just carry a big pocketful of USB sticks. No problems. The output of gpart show is: Code:. Thanks for all the help guys! Thanks for help! The gpart set active method worked for me. Motherboard Asus Z87 Plus. Shame it is. Installation to MBR was painfully slow and disk is painfully again slow when using MBR, which should be the result of 4k aligned disk but I didn't expect to non-aligned disk work 5 times slower than aligned..
Will test with proper hdd setup tomorrow, then.. Last edited by a moderator: Oct 16, I want to hug this thread. Thanks everybody!! Count me in too on this issue.

The boot manager usually has more code in the first track of the disk or within the file system. If only one operating system is installed, the MBR searches for the first bootable active slice on the disk, and then runs the code on that slice to load the remainder of the operating system. When multiple operating systems are present, a different boot manager can be installed to display a list of operating systems so the user can select one to boot.
The remainder of the FreeBSD bootstrap system is divided into three stages. The first stage knows just enough to get the computer into a specific state and run the second stage. The second stage can do a little bit more, before running the third stage.
The third stage finishes the task of loading the operating system. The work is split into three stages because the MBR puts limits on the size of the programs that can be run at stages one and two. Chaining the tasks together allows FreeBSD to provide a more flexible loader. The kernel is then started and begins to probe for devices and initialize them for use.
Once the kernel boot process is finished, the kernel passes control to the user process init 8 , which makes sure the disks are in a usable state, starts the user-level resource configuration which mounts file systems, sets up network cards to communicate on the network, and starts the processes which have been configured to run at startup.
This section describes these stages in more detail and demonstrates how to interact with the FreeBSD boot process. The boot manager code in the MBR is sometimes referred to as stage zero of the boot process. By default, FreeBSD uses the boot0 boot manager. The size and capability of boot0 is restricted to bytes due to the slice table and 0x55AA identifier at the end of the MBR.
If boot0 and multiple operating systems are installed, a message similar to this example will be displayed at boot time:. To create a custom configuration of the MBR, refer to boot0cfg 8. Conceptually, the first and second stages are part of the same program on the same area of the disk. Due to space constraints, they have been split into two, but are always installed together. These two stages are located outside file systems, in the first track of the boot slice, starting with the first sector.
This is where boot0, or any other boot manager, expects to find a program to run which will continue the boot process. The first stage, boot1 , is very simple, since it can only be bytes in size. It knows just enough about the FreeBSD bsdlabel , which stores information about the slice, to find and execute boot2. Stage two, boot2 , is slightly more sophisticated, and understands the FreeBSD file system enough to find files.
It can provide a simple interface to choose the kernel or loader to run. It runs loader, which is much more sophisticated and provides a boot configuration file. If the boot process is interrupted at stage two, the following interactive screen is displayed:. To replace the installed boot1 and boot2 , use bsdlabel , where diskslice is the disk and slice to boot from, such as ad0s1 for the first slice on the first IDE disk:.
If just the disk name is used, such as ad0 , bsdlabel will create the disk in "dangerously dedicated mode", without slices. This is probably not the desired action, so double check the diskslice before pressing Return. The loader is the final stage of the three-stage bootstrap process. The loader is intended as an interactive method for configuration, using a built-in command set, backed up by a more powerful interpreter which has a more complex command set.
During initialization, loader will probe for a console and for disks, and figure out which disk it is booting from. It will set variables accordingly, and an interpreter is started where user commands can be passed from a script or interactively. Finally, by default, loader issues a 10 second wait for key presses, and boots the kernel if it is not interrupted.
If interrupted, the user is presented with a prompt which understands the command set, where the user may adjust variables, unload all modules, load modules, and then finally boot or reboot. Loader Built-In Commands lists the most commonly used loader commands. For a complete discussion of all available commands, refer to loader 8.
Proceeds to boot the kernel if not interrupted within the time span given, in seconds. It displays a countdown, and the default time span is 10 seconds. Immediately proceeds to boot the kernel, with any specified options or kernel name. Providing a kernel name on the command-line is only applicable after an unload has been issued.
Otherwise, the previously-loaded kernel will be used. Goes through the same automatic configuration of modules based on specified variables, most commonly kernel.
This only makes sense if unload is used first, before changing some variables.
