我推荐一下grub，wkx9dragon 写了:发觉对usb的支持不太好，我想做个u盘安装盘，一拷文件就崩溃，比如文件大了，批量复制了，使用管道了，等等。可能用的是不是正式版吧。不得已，还得刻盘安装，试试。
加载ob这种小光盘启动足够了，哈哈。

- Add the ability to revoke keys in sshd(8) and ssh(1).
- Rewrite the ssh(1) multiplexing support to support non-blocking operation of the mux master.
- Add a 'read-only' mode to sftp-server(8) that disables open in write mode and all other fs-modifying protocol methods. (bz#430)
- Allow setting an explicit umask on the sftp-server(8) commandline to override whatever default the user has. (bz#1229)

- Passphrase-protected SSH protocol 2 private keys are now protected with AES-128 instead of 3DES.
- The following significant bugs have been fixed in this release:
- Fixed a minor information leak of environment variables specified in authorized_keys if an attacker happens to know the public key in use.
- When using ChrootDirectory, make sure we test for the existence of the user's shell inside the chroot and not outside. (bz#1679)
- Cache user and group name lookups in sftp-server using user_from_[ug]id(3) to improve performance on hosts where these operations are slow. (bz#1495)
- Fix problem that prevented passphrase reading from being interrupted in some circumstances. (bz#1590)
- Ignore and log any Protocol 1 keys where the claimed size is not equal to the actual size.
- Make HostBased authentication work with a ProxyCommand. (bz#1569)
- Avoid run-time failures when specifying hostkeys via a relative path by prepending the current working directory in these cases. (bz#1290)

- Output a debug log if sshd(8) can't open an existing authorized_keys. (bz#1694)
- Quell tc[gs]etattr(3) warnings when forcing a tty (ssh -tt), since we usually don't actually have a tty to read/set. (bz#1686)
- Prevent sftp(1) from crashing when given a "-" without a command; also, allow whitespace to follow a "-". (bz#1691)
- After sshd(8) receives a SIGHUP, ignore subsequent HUPs while sshd(8) re-execs itself; prevents two HUPs in quick succession from resulting in sshd(8) dying. (bz#1692)
- Clarify in sshd_config(5) that StrictModes does not apply to ChrootDirectory; permissions and ownership are always checked when chrooting. (bz#1532)
- Set close-on-exec on various descriptors so they don't get leaked to child processes. (bz#1643)
- Fix very rare race condition in x11/agent channel allocation

Following this are the instructions which you would have on a piece of paper if you had purchased a CDROM set instead of doing an alternate form of install. The instructions for doing an FTP (or other style of) install are very similar; the CDROM instructions are left intact so that you can see how much easier it would have been if you had purchased a CDROM instead.
Please refer to the following files on the three CDROMs or FTP mirror for extensive details on how to install OpenBSD 4.7 on your machine:

OpenBSD/i386:
- Play with your BIOS options to enable booting from a CD. The OpenBSD/i386 release is on CD1. If your BIOS does not support booting from CD, you will need to create a boot floppy to install from. To create a boot floppy write CD1:4.7/i386/floppy47.fs to a floppy and boot via the floppy drive.
Use CD1:4.7/i386/floppyB47.fs instead for greater SCSI controller support, or CD1:4.7/i386/floppyC47.fs for better laptop support.
If you can't boot from a CD or a floppy disk, you can install across the network using PXE as described in the included INSTALL.i386 document.
If you are planning on dual booting OpenBSD with another OS, you will need to read INSTALL.i386.
To make a boot floppy under MS-DOS, use the "rawrite" utility located at CD1:4.7/tools/rawrite.exe. To make the boot floppy under a Unix OS, use the dd(1) utility. The following is an example usage of dd(1), where the device could be "floppy", "rfd0c", or "rfd0a".- # dd if=<file> of=/dev/<device> bs=32k
- The 4.7 release of OpenBSD/amd64 is located on CD2. Boot from the CD to begin the install - you may need to adjust your BIOS options first. If you can't boot from the CD, you can create a boot floppy to install from. To do this, write CD2:4.7/amd64/floppy47.fs to a floppy, then boot from the floppy drive.
If you can't boot from a CD or a floppy disk, you can install across the network using PXE as described in the included INSTALL.amd64 document. If you are planning to dual boot OpenBSD with another OS, you will need to read INSTALL.amd64.
- Put CD2 in your CDROM drive and poweron your machine while holding down the C key until the display turns on and shows OpenBSD/macppc boot. Alternatively, at the Open Firmware prompt, enter boot cd:,ofwboot /4.7/macppc/bsd.rd
- Put CD3 in your CDROM drive and type boot cdrom.
If this doesn't work, or if you don't have a CDROM drive, you can write CD3:4.7/sparc64/floppy47.fs or CD3:4.7/sparc64/floppyB47.fs (depending on your machine) to a floppy and boot it with boot floppy. Refer to INSTALL.sparc64 for details.
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install will most likely fail.
You can also write CD3:4.7/sparc64/miniroot47.fs to the swap partition on the disk and boot with boot disk:b. If nothing works, you can boot over the network as described in INSTALL.sparc64.
- Write FTP:4.7/alpha/floppy47.fs or FTP:4.7/alpha/floppyB47.fs (depending on your machine) to a diskette and enter boot dva0. Refer to INSTALL.alpha for more details. Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install will most likely fail.
- After connecting a serial port, Thecus can boot directly from the network either tftp or http. Configure the network using fconfig, reset, then load bsd.rd, see INSTALL.armish for specific details. IOData HDL-G can only boot from an EXT-2 partition. Boot into linux and copy 'boot' and bsd.rd into the first partition on wd0 (hda1) then load and run bsd.rd, preserving the wd0i (hda1) ext2fs partition. More details are available in INSTALL.armish.
- Boot over the network by following the instructions in INSTALL.hp300.
- Boot over the network by following the instructions in INSTALL.hppa or the hppa platform page.
- Write miniroot47.fs to the start of the CF or disk, and boot normally.
- Write miniroot47.fs to a USB stick and boot bsd.rd from it or boot bsd.rd via tftp. Refer to the instructions in INSTALL.loongson for more details.
- You can create a bootable installation tape or boot over the network.
The network boot requires a MVME68K BUG version that supports the NIOT and NBO debugger commands. Follow the instructions in INSTALL.mvme68k for more details.
- You can create a bootable installation tape or boot over the network.
The network boot requires a MVME88K BUG version that supports the NIOT and NBO debugger commands. Follow the instructions in INSTALL.mvme88k for more details.
- To install on an O2, burn cd47.iso on a CD-R, put it in the CD drive of your machine and select Install System Software from the System Maintenance menu. On other systems, or if your machine doesn't have a CD drive, you can setup a DHCP/tftp network server, and boot using "bootp()/bsd.rd.IP##" using the kernel matching your system type. Refer to the instructions in INSTALL.sgi for more details.
- After connecting a serial port, boot over the network via DHCP/tftp. Refer to the instructions in INSTALL.socppc for more details.
- Boot from one of the provided install ISO images, using one of the two commands listed below, depending on the version of your ROM.
- ok boot cdrom 4.7/sparc/bsd.rdor> b sd(0,6,0)4.7/sparc/bsd.rd
- ok boot floppyor> b fd()
- Boot over the network via mopbooting as described in INSTALL.vax.
- Using the Linux built-in graphical ipkg installer, install the openbsd47_arm.ipk package. Reboot, then run it. Read INSTALL.zaurus for a few important details.
- src.tar.gz contains a source archive starting at /usr/src. This file contains everything you need except for the kernel sources, which are in a separate archive. To extract:
- # mkdir -p /usr/src# cd /usr/src# tar xvfz /tmp/src.tar.gz
- # mkdir -p /usr/src/sys# cd /usr/src# tar xvfz /tmp/sys.tar.gz
If you already have an OpenBSD 4.6 system, and do not want to reinstall, upgrade instructions and advice can be found in the Upgrade Guide.
Ports Tree
A ports tree archive is also provided. To extract:
- # cd /usr# tar xvfz /tmp/ports.tar.gz# cd ports
The ports/ directory represents a CVS (see the manpage for cvs(1) if you aren't familiar with CVS) checkout of our ports. As with our complete source tree, our ports tree is available via anoncvs. So, in order to keep current with it, you must make the ports/ tree available on a read-write medium and update the tree with a command like:
- # cd [portsdir]/; cvs -d [email protected]:/cvs update -Pd -rOPENBSD_4_7
Note that most ports are available as packages through FTP. Updated packages for the 4.7 release will be made available if problems arise.
If you're interested in seeing a port added, would like to help out, or just would like to know more, the mailing list [email protected] is a good place to know.

解决了，办法比较老土：crzyfish 写了:今天用U盘grub启动NetBSD的光盘了，就是安装的时候选从CD-ROM安装选不了，然后又回来用虚拟机试了试，
mentohust编译了后NetBSD可以上教育网了，貌似还不错~
再努力试试~呵呵~
PS:我记得以前用ISOEMU（DOS虚拟光驱软件）安装OpenBSD的时候选文件在cdrom是没问题的。。。不懂了呵呵
ISOEMU做启动更是启动不了，
但是用另一个U盘装i386文件夹，然后主U盘启动nb的iso，在shell先mount /dev/sd1e /mnt 然后再运行安装程序sysyinst
当进入选从哪里安装的时候，选从目录：/mnt
即可……
还是fat吃得比较开~在线用户
