Confessions of a cat

UPDATE: (2009/june/10th) - All the below mentioned things are still valid, however I had no luck with installing using this method on my usb drive. I did, however, found the http://usboot.org/ website, and their latest (v. 2.10 this time) version works wonderfully for me. What you need to do to get usboot v2.10 working, in a nutshell:

1. register on their website (you need this later)
2. download the program (a zip file with lots of batch files and stuff)
3. If you do not have a multiboot capable pc, install vmware, or parallels desktop, or qemu or virtualbox (latter 2 are free) - these are virtual machine emulators
4. get a clean copy of windows xp with sp2 or sp3 integrated
5. install this windows in any of the abpve mentioned programs
6. once install is done you may wish to install some drivers for the virtual machine (not required)
7. install usboot, and follow its user guide closely - default options are good
8. with usboot the last step is to copy the files to the usb hard drive - this should be a usb hard drive and not a flash drive, and it should be formatted to fat32 (ntfs puts more burden on it). test if it’s bootable on your computer (check bios settings) - if no luck, use the hp usb disk format tool, that might help.

Many of us have got rid of windows in recent years. Some of you have switched to linux (ubuntu, debian, redhat, you name it), and some of you have turned to Apple’s OS X. Both of them are a better choice in my humble opinion. Anyways, sometimes you just want to play a game that’s only available on windows, or you want to access some hardware for which only a windows application / driver exists. Or you have a PIC programmer and you like Winpic800 (the free programming app), but it only runs on windows.

Many of you have several computers sitting around at home, and you can just keep a windows install on one of them. However if you’re like me, you have one “workhorse” machine, that you spend most of your time in front of. It would be good to have windows at hand when you need it without messing with your internal drive(s).

The net is / was full of articles (from M$) which say that booting windows xp from external USB storage is not possible. You may have heard about BartPE and Windows PE - they are essentially live windows XP images which allow you to run windows xp from a CD / DVD (or even USB) however they are not really the “real deal” - as you are limited in what you can do with them.

Now I needed windows for some hacking with applications that can only be run on windows. But since I use a nice OSX system which I do not want to fuck up and share its space with XP: this solution is the best for me. And maybe for you too.

Csak két kép, hogy megmaradjon majd az utókornak:

Az eredeti URL ahonnan származik

Ezek a tag-ek a legjobbak, azon belül is a “romák elleni támadások” az egyik kedvencem (mintha fordítva lenne általában, de végülis mindegy, nem kicsit részrehajló népség). A bankrablás a másik kedvencem, meg az iskolai agresszió is, és ne feledjük a “rasszizmus”-t sem, mert az nagyon tuti. A Demszky meg Zushlag cumókat inkább nem is emlegetem. Kellenek a bűnbakok (csak ez már nem működik). Ej

If you want to do that, you will soon find an app called ‘MacSFV’ but its PPC only and the latest update done to it is in 2003. So what to do now?

Fortunately the Mac has a BSD unix system as its underpinning with lots of good and usable command line tools. One of them is called ‘cksum’. Although it does not generate straight sfv files (which uses crc32 checksums for each file listed in them) but with a little trick you can use it. Here’s a simple example, using multi volume rar files:

cksum -o 3 *.part*.rar | perl -wane 'printf "%s %08x\n", $F[2], $F[0]‘ > checksums.sfv

It basically pipes the output from cksum to a small perl program that formats the output as in the sfv file standard (if there’s a standard like that :)). If you want to be sure that this is compatible with windows systems, use \r\n instead of \n in the printf fomratting call above.

Also thanks for Zsolt Muller for his article. Nice fella, since he uses drupal with its default theme for his blog
