rugxulo,
I've downloaded dosbox. Can you tell me basically how to use it to play the mini dos games? I mean, those boot-sector mini games... |

Like Privalov's TetrOS?: boot tetros.bin works for me (DOSBox 0.65, Win XP).
However, that is mainly intended to be written to a floppy (resets the game upon ESC, so you'll have to reboot if you want to quit). There are other small games, non-bootable, (like the 360-byte Tetris and Invaders) that don't require you to do anything besides run 'em.  |

The status window error concerns me. I've tested timers from here , vid says 'accurate timing in DOS box under windows is impossible' i think he is right. |

Well ,
long delay are not accurate for multitasking nature of 32bit OS , i have ask you how much delay for this reason. Bios INT 15H also isn't accurate ,either pure DOS or DOS box or emulator. The best timer is RDTSC instruction if you have a CPU that support it, PIT is accurate , and with some trick also in XP |

It's true, the DOSBox 0.70 status window does whine, but the program seems to work (at least, what's it supposed to do??). Anyways, take it up with the DOSBox guys (IRC: #dosbox on Freenode). If you want to try real DOS, get FreeDOS (they updated the .ISOs recently).
P.S. I think DOSBox only emulates a 486/DX2 (i.e. no Pentium and therefore no RDTSC). But it does have CPUID.

Bios INT 15H, AH=86h doesn't work in XP at all and doesn't work correctly in DOSBOX (at least in version 0.65. I didn't try version 0.70). But it works very well in plain DOS and accurately enough in Windows98. Try another delay code for compatibilty with XP.

Hello all,
Can i have on windows xp console 8x8 pixels characters? I'm using this small piece of code, it's working on Dosbox emulator but not on xp console.. Code:
mov ax,1202h ; select 400 scan line mode
mov bl,30h
int 10h
mov ax,3 ; select 80 x 25 16 colour mode
int 10h
mov ax,1112h ; load 8x8 character set into RAM
mov bl,0
int 10h

It's most likely working in WinXP as well, but if you are using CMD.EXE as shell, it will quickly restore the previous setting once your program has terminated. To keep the 8x8 font after your program has exited, either run it from a DOS shell (command.com, 4DOS.com) or change to the 50 lines resolution the "dump" way in cmd.exe: mode con lines=50 |

using dosbox emulator, cwsdpmi.exe must be run immediately before fasm.exe every time. Is there a way to run cwsdpmi only once?
