Blesser ======= Version 1.00 Date 04-JUL-98 License Freeware, all rights reserved. Description ~~~~~~~~~~~ As a developer, I find I often have to switch OS (NT4 or Win98) to test things in each enviroment. There are two problems with that, you have to stay around long enough to select the new OS from the boot menu rather than get a beer. And then for each reboot you have to select the OS again if it is not the default. This program does two things when run. It changes the default operating system to be the opposite to the system in which it is run. Then it reboots. Originally a I used a batch file to change the boot.ini file but this couldn't reboot the PC. Warnings ~~~~~~~~ This is just a little ditty I knocked up to fix my problem, I have tried it out on various PCs covering Win95, Win98, NT5, NT4, SCSI and IDE. The program modifies C:\BOOT.INI so you must have a valid configuration and sufficient backups before you run the program. In particular you should have a bootable floppy that can access your c drive (watch out for FAT32, you need DOS7.1), if all goes wrong you need to restore you BOOT.INI file, YOU should back it up. If run in 95/98 it identifies the first partion without a : (colon) and copies it to the default entry. In the eg INI file below "default=C:\" becomes "default=multi(0)disk(0)rdisk(2)partition(1)\WINNT" If run in 95/98 it identifies the first partion without a : (colon) and copies it to the default entry. In the eg INI file below default=multi(0) disk(0)rdisk(2)partition(1)\WINNT" becomes "default=C:\" [boot loader] timeout=5 default=C:\ [operating systems] C:\="16 Bit Windows" multi(0)disk(0)rdisk(2)partition(1)\WINNT="WinNT" multi(0)disk(0)rdisk(2)partition(1)\WINNT="WinNT [VGA mode]" /basevideo /sos And of course the usual legalese, I will accept no responsibility for this program what it does directly or indirectly. Don't use it to control a power station or a life support system! Installation ~~~~~~~~~~~~ Just copy the EXE where you want it and if you like make a shortcut someplace, if you are running two OSs you must know what your doing. The EXE requires VB5 runtime files (not included), There cannot be a PC out there without VB5 runtime files. If not go look on Microsofts' site for MSVBVM50.EXE which is supposed to install the neccesary stuff. The Name ~~~~~~~~ This utility is named after a little ditty on the MAC that allowed switching between Systems 6 & 7. Support ~~~~~~~ It's free what do you expect, you can email me on chris_a@usa.net and I will have a look, but no guarantees. History ~~~~~~~ 04/07/98 V1.00 First public release, only one known problem, sometimes the reboot of NT5.0 (beta 1) only causes a logoff.
