Short: Little Bootblock-Util Installer Author: NOMAD of QUARTEX Uploader: aminet aminet net Type: util/boot Version: 2.0 Architecture: m68k-amigaos %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % NOMAD UTILITY BOOT V2.0 % % CODED BY N.O.M.A.D OF QUARTEX % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Oh no you say !.Not another utility boot !.Well it is one of the only things that i really enjoy coding!.Squeezing all that code into 1k is a challenge!.There have been a few new util boots on the scene since my last one (V1.0).They are all good piece`s of code so its really upto you which one you use !. This boot Detects virus`s ,and will warn you if it thinks one is present,tell you the current state of fastmem extra chip mem , drives df0: to df3: ,turns fast memory on and off , extra chip mem on / off,drives on and off, performs a true hard reset,kills virus,toggles filter, will switch between PAL / NTSC mode and will SAFELY install itself on any disk.(Unlike one new boot i can mention!).The docs on each option follow !!!!. The bootprogram can be exited by pressing the left mouse button or it will auto exit after approx 20 secs to the cli UNLESS a virus is detected then it just waits until the left mouse button is pressed or you kill the virus. System info (2nd & 3rd lines of display) FASTMEM:??? Tells you if fast memory is installed 1 MEG CHIP:???? Tells you if extra chip mem is installed DF1:??? DF2:??? DF3:??? Tells you which drives are enabled Just some notes about each option.. The keys need to be pressed down firmly.If the option you chose does not register try the key again... Key F1 ... Fastmem Off If your amiga has ANY extra memory installed this option will make it invisible to the execbase.It does not alloc all the fast memory like other boots,but actually traps the reset routine while it checks for extra mem.Then it fools it into thinking there is only chipmem available. Because of this the memory will stay off until you use Memory on-option F3 or any program kills the execbase. Note: this version will still allow the 1 meg chip mem to be used,most other boots turn it off as well !!!!!. Key F2 ... Fast/Chip Off This option will do exactly the same as option F1 ,except that only the 512k of chipmem will be available to you. All extra Fastmem and Chipmem is disabled Key F3 ... All Mem on This will turn back on all the extra memory that key F1-F2 (Memory off) disabled. Key F4 ... Kill Drives This option will fool execbase in thinking all drives are off.This saves upto 25k of memory for each drive.Useful for low mem conditions.Once this option is selected the bootblock will exit to the CLI.After reseting your amiga the drives will be available to the system again. Key F5 ... Hard Reset - Viri Reset This performs a true hard reset.The equivalent of powering off your amiga!.All hardware and the amiga will be returned to the state they were in when you powered up your amiga. Note: If the screen flashes red and the message " A VIRUS HAS BEEN DETECTED! " appears just above the credit This option will alter to VIRI RESET . Using this option will kill the possible virus in memory.I say possible because as you may know,reset monitors etc use the same vectors as a virus.If however you have not installed such a program then it IS a virus..Kill it!. Key F6 ... Install Boot This will safely install the utility boot on any disk that is inserted in df0: (Do not worry about the screen when installing).No need for a separate install program once it is on one of your disks. Key F7 ... Toggle Filter This will turn the Low pass filter on and off.Music will be clearer with it off. Key F8 ... Tog Pal/Ntsc This option will toggle between pal and ntsc mode only if you have the obese angus installed in your machine.Useful for checking games in either mode. This boot has been tested on all kickstart versions. 1.0 to 2.0.Because all the routines are LEGAL it should work on any kickstart.... Please use this utility boot .. Thank you ..
