Screenshots in DOS
Operating systems : MS-DOS 6.0+, FreeDOS 1.0+
There are several programs for taking screenshots in DOS. SNARF, for instance. Using this application succeeded in taking screenshots in most of the cases. Also, the screenshots' quality (.BMP files) by SNARF results to be the highest among the programs tested: ScreenThief, VideoThief, FLIP, GRABBER, SNARF.
Using SNARF with default settings is straightforward, but there is a shortcoming - SNARF always saves screenshots to the folder where the user is currently in. That could be inconvenient or unacceptable. And there is no obvious way to change it. But there is a roundabout option. The initial idea had been found on this page. The result based on it:
1. SNARF [ Download ]
2. Open SNARF.EXE in a text editor in text mode (not hex), find snarf000.bmp and replace it for s:scn000.bin
3. Create a batch file, S.BAT for example, where besides a string for starting SNARF.EXE will be a command assigning the path to the folder screenshots will be saved into to a virtual drive S: The folder and path may be any:
SUBST S: C:\SCREENS\
4. Start SNARF:
S [or S.BAT]
5. To take a screenshot:
Alt + S
There will be two beeps. The first at the beginning and the second one as a sign the process has completed successfully. After the screenshots are taken, go to the folder where they are saved in and replace the file extensions from .BIN to .BMP
SNARF - Freeware.

Migrating an IMAP account from one IMAP server to another [ 1 ] / Linux, command line: imapsync --host1 imap.this.com --user1 email@example.com --passfile1 /home/user/imap/passwordfile1 --ssl1 --host2 imap.another.com --user2 firstname.lastname@example.org --passfile2 /home/user/imap/passwordfile2 --ssl2 --skipsize --allowsizemismatch - There is a web site (example.com) and an email box (email@example.com) hosted at a web hosting company. The IMAP server: imap.this.com. The IMAP server supports SSL. - The example.com web site is to be transfered to another web hosting company. So is the firstname.lastname@example.org box with all its contents and keeping its folders structure. The IMAP server of another web hosting company: imap.another.com. The IMAP server supports SSL. 1. Set up an email box named email@example.com and a password to it on the server of the web hosting company the firstname.lastname@example.org mailbox is to be transfered to - from the previous web hosting company. 2. Create two text files in /home/user/imap/: passwordfile1 with the password for the mailbox on the first IMAP server and passwordfile2 with the password for the mailbox on the second IMAP server. 3. chmod 600 /home/user/imap/passwordfile1 4. chmod 600 /home/user/imap/passwordfile2 5. Install imapsync 6. Run imapsync Imapsync transfers a mailbox - keeping its folders structure - from imap.this.com to imap.another.com. SSL is used to enable encryption and passwords are saved to protected files (chmod 600). Migration between two email service boxes may happen to require to make use of more imapsync options [ 2 ]. Like transfering contents of one Gmail.com box to another demands to have "--port1" and "--port2" specified: imapsync --host1 imap.gmail.com --port1 993 --user1 email@example.com --passfile1 /home/user/imap/passwordfile1 --ssl1 --host2 imap.gmail.com --port2 993 --user2 firstname.lastname@example.org --passfile2 /home/user/imap/passwordfile2 --ssl2 --skipsize --allowsizemismatch [ 1 ] A simple and common case: contents of one email box are transfered to another, empty mailbox. But there can be more complicated ones like: Gmail to Google Apps Email Migration and Moving to Google Apps with imapsync. [ 2 ] For more command options: Migrate mail from one server to another with imapsync and imapsync(1) - Linux man page.
A : Installing Arachne web browser on a disk created in RAM - Arachne runs the fastest this way. RAM size should allow for a RAM disk of 6 MB or more. In order to install and set up Arachne web browser for internet connection via Ethernet, there have to be several programs at hand: 1. Arachne web browser [ Download ] 2. If Arachne web browser is to be used for surfing web pages with character encoding other than Latin for West European languages, visit www.glennmcc.org/apm/ to find available character set packages and download the necessary one. 3. Mouse driver, mouse.com for instance [ Download ] 4. Packet driver for Ethernet network card: http://www.crynwr.com/drivers/ http://www.georgpotthast.de/sioux/packet.htm 5. Microsoft Network Client 3.0 [ Download ] 6. NDIS 2.0 driver for Ethernet network card. For example: Realtek RTL8029AS [ Download ]. Drivers for other network cards may be found, for instance, on web sites of Ethernet cards manufacturers. 7. Archivers. For example, PKZIP [ Download ] and PKUNZIP [ Download ] 8. If it is not MS-DOS 6.0+ to be used, QEMM97 [ Download ] 9. If it is not MS-DOS 6.0+ to be used, TDSK [ Download ] Installing and setting up Arachne web browser, step by step: 1. Create a RAM disk. Which drive letter will be assigned to it comes from the assumption that A: and B: go to floppy drives (even if there is only one, both letters will be reserved anyway), C: goes to the first active primary MS-DOS partition on the first physical hard disk. If there are more disks, then there will be as many letters used consecutively as to name them all. Unless there are no devices installed using DRIVER.SYS or similar drivers, the next drive letter will be assigned to the RAM disk. In order to be sure, after having the relevant string for making RAM disk added to CONFIG.SYS (See below), computer could be restarted and what letter is assigned to the RAM disk checked by experiment. In this case, it is E: Depending on RAM size it needs to be decided how many megabytes can be reserved for RAM disk. Basically, the more the better. Since, for instance, web browser cache is going to swell during prolonged and intensive use within a session. In this example the RAM disk is 12 000 KB. The maximum size for RAMDRIVE.SYS MS-DOS driver is 32 767 KB, the one of TDSK - 64 MB. In order to create such a disk, the string has to be added somewhere in the middle of CONFIG.SYS as follows: DEVICE=C:\DOS\RAMDRIVE.SYS 12000 512 512 /E 2. Create a folder, for example C:\DRIVERS\. Put there: a mouse driver, for instance mouse.com, a packet driver for Ethernet network card and a NDIS 2.0 driver for Ethernet network card. 3. Add a string starting mouse driver to AUTOEXEC.BAT. Specify there the full path to the driver, may be any: LH C:\DRIVERS\MOUSE.COM 4. Prepare installation floppies of Microsoft Network Client 3.0: DSK3-1.EXE -d A: DSK3-2.EXE -d A: 5. Start setup.exe from the first floppy and begin Microsoft Network Client 3.0 installation. Installation is starting. Press Enter to continue Select folder for Microsoft Network Client 3.0 to be installed to. It may be any or the suggestion of the installer may be left as it is - in the case discussed it is left as it is.
