The files of this archive contain some little modifications, relatives to: 1. INT 8 (time management, little anim in the topbar, cursor flashing); 2. "pciinfo " command. Note that the system32.asm file contains the modifications of DarkSpirit, about ramdisk module. On my box, it seems to be running correctly, but I'm not sure about the infos given by the pciinfo command. Is this correct ? Anyway, it doesn't switch to the CRASH SCREEN :) To install these new files, 1. unzip them in the /system32 ; 2. backup the following files: ./system32.asm ./terminal/terminal.inc ./sysrout/sr32.inc ./sysrout/sr33.inc ./sysrout/sr34.inc ./sysrout/sr35.inc 3. rename the files ./system32-RC1.asm in ./system32.asm ./terminal/terminal-RC1.inc in ./terminal/terminal.inc ./sysrout/sr*-RC1.inc in ./sysrout/sr*.inc 4. You can rebuild V2_OS V0.64b on a floppy disk with your preferred method (make.bat or Makefile) Regards.
