I also found something strange in keyboard.cpp case 0xf2: /* Identify keyboard */ KEYBOARD_AddBuffer(0xfa); /* Acknowledge */ KEYBOARD_AddBuffer(0xab); /* ID */ KEYBOARD_AddBuffer(0x41); break; In my opinion it should be: case 0xf2: /* Identify keyboard */ KEYBOARD_AddBuffer(0xfa); /* Acknowledge */ …

Maybe that's the way: keyboard.cpp: case 0xff: /* reset */ LOG(LOG_KEYBOARD,LOG_NORMAL)("AUX reset"); KEYBOARD_AddBuffer(AUX|0xfa); /* ack */ Mouse_AutoLock(false); AUX_Reset(); PIC_AddEvent(AUX_ResetDelay,RESETDELAY >> 1); break; static void AUX_ResetDelay(Bitu val) { // keyb.reset=false; KEYBOARD_ …

Hi, since I developed software for KVM systems which have to emulate keybord and mouse, I can tell you the following: PS/2 Keyboard: After power on it sends 0xAA after finishing the selftest. On a reset command (0xFF) it responce with 0xFA (ACK) and after a short time with 0xAA for a good selftest. …

@h-a-l-9000 I think at the end of your diff file is something wrong. Fontload is still only possible for VGA and EGA. So the if (CurMode->type==M_TEXT) { - if (IS_VGA_ARCH) should still be inside. (with || for EGA) Beard P.S.: At the moment I can not compile DOSBox :( so I can not really test …

Hi ripsaw8080, that's the problem with vgaonly! It is a 8 by 8 font and it is handled like a 8 by 9 font. So I get also the "one missing pixel" on the screen. With svga_s3 it is handled correct. I attach a small game which shows it easily. Copy it in the same directory as the emulator. If the …

@ripsaw8080 you are right. At my first test I used vgaonly as machine. With svga_s3 and your scanres it works in both, windowed and fullscreen version. Beard

@ripsaw8080 I tested your small tools. I don't see any better behaviour. The same thing happens as with my program. If you run cga.com for example, you get a box inside the box. Oh, when the DOSBox runs in fullscreen mode, than it works if I load scanres before. And with vgaonly it is not working …

@wd On a real PC booted with FreeDOS or in a fullscreen DOS box of Win98 it works correct: I see 320 by 200 pixels on the fullscreen and not only on half of the screen. @ripsaw8080 That's strange, because when I make a boot disk image with FreeDOS and run it with Bochs 2.4.1 I got the same result as …

Hi QBix, you are right. I just updated the files and attached them here. Now it is reduced to the minimum. It happens when the user font is activated. I had only one short fast look into the DOSBox sourcecode, so I can not say anything about it. It looks that the change of the scanlines has no …

It has nothing todo with the rouitines I showed before. I'd just written a small test program. For my suprise it was possible to switch to the 40x25 mode without problems. So I included the next step. I installed the own characterset void CGRAMToVGA(void) { /* * Copy the MZ-CharacterFont (CG-RAM) …

@QBix the scanline stuff is neccessary to tell the card to use the 8x8 character set. Beard

@h-a-l-9000 excuse me, but the command ldgfxrom is not available inside the DOSBox. Please give me a hint. @QBix Hm. it is not easy to describe. For me it looks like that the switching to 40x25 mode works, but the DOSBox window is not effected by this resolution switch. I'll write a small test …

@MinMax If you read my posting carefully, you can read that I tried already all available -machine values. @h-a-l-9000 I'll give it a try. Thanks Beard

Hi, I'm a newbie with a special problem. I have a problem with an emulator for my first home computer. A SHARP MZ-700. It works perfect, but.... only below WinNT. To use it in Windows XP I tried several DOS emulators and VMs. All with the same effect, that the graphic resolution is not working as in …
