@ -102,18 +103,43 @@ Q: My CD-ROM doesn't work.
A: To mount your CD-ROM in DOSBox you have to specify some additional options
when mounting the CD-ROM.
To enable CD-ROM support (includes MSCDEX):
- mount d f:\ -t cdrom
To enable low-level CD-ROM-support (uses ioctl if possible):
- mount d f:\ -t cdrom -usecd 0
To enable low-level SDL-support:
- mount d f:\ -t cdrom (windows)
- mount d /media/cdrom -t cdrom (linux)
In some cases you might want to use a different CD-ROM interface,
for example if CD audio does not work:
To enable SDL-support (does not include low-level CD access!):
- mount d f:\ -t cdrom -usecd 0 -noioctl
To enable ioctl access using digital audio extraction for CD audio
(windows-only, useful for Vista):
- mount d f:\ -t cdrom -ioctl_dx
To enable ioctl access using MCI for CD audio (windows-only):
- mount d f:\ -t cdrom -ioctl_mci
To force ioctl-only access (windows-only):
- mount d f:\ -t cdrom -ioctl_dio
To enable low-level aspi-support (win98 with aspi-layer installed):
- mount d f:\ -t cdrom -usecd 0 -aspi
- mount d f:\ -t cdrom -aspi
In the commands: - d driveletter you will get in DOSBox
- f:\ location of CD-ROM on your PC.
- 0 The number of the CD-ROM drive, reported by mount -cd
See also the question: The game/application can't find its CD-ROM.
- 0 The number of the CD-ROM drive, reported by "mount -cd"
(note that this value is only needed when using SDL
for CD audio, otherwise it is ignored)
See also the next question: The game/application can't find its CD-ROM.
Q: The game/application can't find its CD-ROM.
A: Be sure to mount the CD-ROM with -t cdrom switch, this will enable the
MSCDEX interface required by DOS games to interface with CD-ROMs.
Also try adding the correct label (-label LABEL) to the mount command,
where LABEL is the CD-label (volume ID) of the CD-ROM.
Under Windows you can specify -ioctl, -aspi or -noioctl. Look at the
description of the mount command in Section 4 for their meaning and the
additional audio-CD related options -ioctl_dx, ioctl_mci, ioctl_dio.
Try creating a CD-ROM image (preferably CUE/BIN pair) and use the
DOSBox-internal IMGMOUNT tool to mount the image (the CUE sheet).
This enables very good low-level CD-ROM support on any operating system.
Q: The mouse doesn't work.
@ -135,6 +161,9 @@ A: Be sure that the sound is correctly configured in the game. This might be
If you still don't get any sound set the core to normal and use some lower
fixed cycles value (like cycles=2000). Also assure that your host operating
sound does provide sound.
In certain cases it might be useful to use a different emulated sound device
like a soundblaster pro (sbtype=sbpro1 in the DOSBox configuration file) or
the gravis ultrasound (gus=true).
Q: The sound stutters or sounds stretched/weird.
@ -142,52 +171,41 @@ A: You're using too much CPU power to keep DOSBox running at the current speed.
You can lower the cycles, skip frames, reduce the sampling rate of
the respective sound device (see the DOSBox configuration file) or
the mixer device. You can also increase the prebuffer in the configfile.
If you are using cycles=max or =auto, then make sure that there no
If you are using cycles=max or =auto, then make sure that there is no
background processes interfering! (especially if they access the harddisk)
Q: I can't type \ or : in DOSBox.
A: This is a known problem. It only occurs if your keyboard layout isn't US.
A: This can happen in various cases, like your host keyboard layout does not
have a matching DOS layout representation (or it was not correctly detected),
or the key mapping is wrong.
Some possible fixes:
1. Switch the keyboard layout of your operating system.
2. Use / instead.
3. Open dosbox.conf and change usescancodes=false to usescancodes=true.
4. Add the commands you want to execute to the "configfile".
5. Change the DOS keyboard layout (see Section 7 Keyboard Layout).
6. Use ALT-58 for : and ALT-92 for \.
7. for \ try the keys around "enter". For ":" try shift and the keys
between "enter" and "l" (US keyboard layout).
8. Try keyb.com from FreeDOS (http://projects.freedos.net/keyb/).
Look for keyb2.0 pre4 as older and newer versions are known to
have a bug in the loader routines.
1. Use / instead, or ALT-58 for : and ALT-92 for \.
2. Change the DOS keyboard layout (see Section 7: Keyboard Layout).
3. Add the commands you want to execute to the [autoexec]-section

4. Open the DOSBox configuration file and change the usescancodes entry.
5. Switch the keyboard layout of your operating system.
Note that if the host layout can not be identified, or keyboardlayout is set
to none in the DOSBox configuration file, the standard US layout is used.
In this configuration try the keys around "enter" for the key \ (backslash),
and for the key : (colon) use shift and the keys between "enter" and "l".

Q: The game/application can't find its CD-ROM.
A: Be sure to mount the CD-ROM with -t cdrom switch, this will enable the
MSCDEX interface required by DOS games to interface with CD-ROMs.
Also try adding the correct label (-label LABEL). To enable lower-level
CD-ROM support, add the following switch to mount: -usecd #, where # is
the number of your CD-ROM drive reported by mount -cd. Under Windows you
can specify -ioctl, -aspi or -noioctl. Look at the description elsewhere
in this document for their meaning.

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

@ -2,13 +2,10 @@ Some notes about porting DOSBox to systems with certain restrictions,
like handheld devices.
If memory is a constraint:
- in paging.h reduce the size of the TLB:
#define TLB_SIZE (64*1024)
the 64 gives access to the first 256mb of linear memory
drawback: some protected mode games won't work then
- in paging.h out-comment the USE_FULL_TLB define to enable special
TLB linking code that uses less memory
drawback: none (the code is not heavily tested though)
gain: reduces memory requirements about ~15mb
TODO: limit vmemory access to the size of the TLB,
otherwise games which use >256mb vaddresses will crash badly

drawback: some apps might not work whith large directory trees
drawback: some apps might not work with large directory trees
gain: ~1mb per mounted drive
- remove the GUS emulation (gus.cpp, especially GUSRam[1024*1024] )
drawback: no gravis ultrasound
gain: reduces memory requirements about 1mb
- in vga.h reduce the size of the emulated graphics memory:
#define VGA_MEMORY (1*1024*1024)
- reduce the size of the emulated graphics memory:
see the memory sizing in SVGA_Setup_*, especially the defaults
in vga_s3.cpp's SVGA_Setup_S3Trio
drawback: some graphics modes won't work then
[EDIT: many modes won't work due to pixel caches]
gain: reduces memory requirements about 1mb
TODO: get this to actually work;
remove the respective svga modes, adapt some svga registers
gain: reduces memory requirements
TODO: fully check this, introduce hard limits
If speed is a constraint:
- see if the simple core is faster, possibly remove the normal core
