I'm trying to test SWARM in a Vbox-FreeBSD environment.
I had prepared an ISO of my USB pendrive that just contains SWARM.
I'm using the FreeBSD image from my host's harddrive.
Both images are connected/assigned in VBox under mass-storages -> CDROM and USB.
Since I dont want to install anything, I did not 'assign' a VDI for the FreeBSD-Vbox.
So, I booted FreeBSD login in as root... and am getting lost there...
Now I do know how to mount stuff in linux, I know my ways around...
However, with FreeBSD... I am getting lost..
hi. I am newbie in Unix. I wanted to install Free BSD 5.2.1 to my computer which winXp was already installed. But i couldn't.
I chose Standard. Then it said you are going to use dos style fdisk partitioning. Then a window displayed begining like this.

Hello there,
My mulithreaded application (which is too large to represent the source code here) is crashing after installing FreeBSD 7.1-RELEASE/amd64.
It worked properly on others machines (Dual Cores with 4GB of RAM - FreeBSD 6.2-RELEASE/i386).
The current machine has 2x Core 2 Duo... (1 Reply)
Hi all,
Can anybody help me with how I can connect a usb pendrive or external disk to a Sun Server which runs on Solaris 9? I am able to connect the usb drive to a windows server easily and copy files but am wondering if it is possible to do that with Solaris.
Any help will be appreciated. thanks. (3 Replies)
Hi,
I am using compaq t5207tu model with 60gb harddisk and 2.5gb RAM.Its dual boot-Windows XP and Solaris. I tried installing SUN xVM on solaris to make client -server architecture (32 bit processor and 32 bit OS ) -guest OS (solaris 10)on host OS(Solaris 10). But whenever i try to install... (1 Reply)
Hi Gurus,

Holla,
I have been trying to install a recent distro, with a minimum X such as jwm, but unfortunately my cdrom is broken and I can only boot the USB port, with a pendrive.
AMD K6 3D is today too old for being for linux.
Is there an image of slackware than runs that processor and that can... (5 Replies)
I've "installed" LM 19.1 to a PNY 16Gb(2.0) pendrive. I have a few issues that I'd like to resolve. First and foremost, the O.S. experiences "lagging" issues and to a lesser degree, freezing. Example: Complete "boot-up" (from start to complete "home" page) can take upwards of 7 mins. Then when... (10 Replies)

aout
AOUT(4) BSD Kernel Interfaces Manual AOUT(4)NAME
aout -- kernel support for executing binary files in legacy a.out format
SYNOPSIS
kldload a.out
DESCRIPTION
The a.out(5) executable format was used before the release of FreeBSD 3.0. Since i386 was the only supported architecture at that time,
a.out(5) executables can only be activated on platforms that support execution of i386 code, such as i386 and amd64.
To add kernel support for old syscalls and old syscall invocation methods, place the following options in the kernel configuration file:
options COMPAT_43
options COMPAT_FREEBSD32
The COMPAT_FREEBSD32 option is only required on 64-bit CPU architectures.
The aout.ko module needs to be loaded with the kldload(8) utility in order to support the a.out(5) image activator:
kldload aout
Alternatively, to load the module at boot time, place the following line in loader.conf(5):
aout_load="YES"
The a.out(5) format was mainstream quite a long time ago. Reasonable default settings and security requirements of modern operating systems
today contradict the default environment of that time and require adjustments of the system to mimic natural environment for old binaries.
The following sysctl(8) tunables are useful for this:
security.bsd.map_at_zero Set to 1 to allow mapping of process pages at address 0. Some very old ZMAGIC executable images require
text mapping at address 0.
kern.pid_max Old versions of FreeBSD used signed 16-bit type for pid_t. Current kernels use 32-bit type for pid_t, and
allow process id's up to 99999. Such values cannot be represented by old pid_t, mostly causing issues for
processes using wait(2) syscalls, for example shells. Set the sysctl to 30000 to work around the problem.
kern.elf32.read_exec Set to 1 to force any accessible memory mapping performed by 32-bit process to allow execution, see mmap(2).
Old i386 CPUs did not have a bit in PTE which disallowed execution from the page, so many old programs did
not specify PROT_EXEC even for mapping of executable code. The sysctl forces PROT_EXEC if mapping has any
access allowed at all. The setting is only needed if the host architecture allows non-executable mappings.
SEE ALSO execve(2), a.out(5), elf(5), sysctl(8)HISTORY
The a.out(5) executable format was used on ancient AT&T UNIX and served as the main executable format for FreeBSD from the beginning up to
FreeBSD 2.2.9. In FreeBSD 3.0 it was superseded by elf(5).
AUTHORS
The aout manual page was written by Konstantin Belousov <kib@FreeBSD.org>.
BUGS
On 64bit architectures, not all wrappers for older syscalls are implemented.
