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 the most basic CD-ROM support:
To enable CD-ROM support (includes MSCDEX):
- mount d f:\ -t cdrom
To enable low-level SDL-support:
To enable low-level CD-ROM-support (uses ioctl if possible):
- mount d f:\ -t cdrom -usecd 0
To enable low-level ioctl-support(win2k/xp/linux):
- mount d f:\ -t cdrom -usecd 0 -ioctl
To enable low-level SDL-support:
- mount d f:\ -t cdrom -usecd 0 -noioctl
To enable low-level aspi-support (win98 with aspi-layer installed):
- mount d f:\ -t cdrom -usecd 0 -aspi
In the commands: - d driveletter you will get in DOSBox
- f:\ location of cdrom on your PC.
- f:\ location of CD-ROM on your PC.
- 0 The number of the CD-ROM drive, reported by mount -cd

Q: The keyboard lags.
A: Lower the priority setting in the DOSBox configuration file

try lowering the cycles.
Q: The cursor always moves into one direction!
A: See if it still happens if you disable the joystick emulation,
set joysticktype=none in the [joystick] section of your DOSBox
configuration file. Maybe also try unplugging any joystick.
If you want to use the joystick in the game, try setting timed=false
and be sure to calibrate the joystick (both in your OS as well as
in the game or the game's setup).
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 or -aspi. Look at the description elsewhere in this
document for their meaning.

Try creating a CD-ROM image (preferably CUE/BIN pair) and use the

good low-level CD-ROM support on any operating system.

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
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
- in render.h lower the scaler integration:
#define RENDER_USE_ADVANCED_SCALERS 1
or
#define RENDER_USE_ADVANCED_SCALERS 0
drawback: complex scalers and the scaler cache are disabled,
be sure to test if this affects speed!
with define RENDER_USE_ADVANCED_SCALERS==0 most simple
scalers are disabled as well, some graphics modes won't
work due to reduced cache sizes
gain: ~2mb with RENDER_USE_ADVANCED_SCALERS==1
~5mb with RENDER_USE_ADVANCED_SCALERS==0
- in dos_system.h reduce the drive cache entries:
#define MAX_OPENDIRS 256
drawback: some apps might not work whith 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)
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
If speed is a constraint:
- see if the simple core is faster, possibly remove the normal core
set the simple core as default
drawback: one game is known to not work with the simple core;
the simple core does only work for games which don't use paging
(when paging is requested the normal core is used automatically)
gain: the simple core should be somewhat faster
TODO: add possibility to easily remove the normal core, use fullcore fallback
- raise the default frameskip value
drawback: minor graphics smoothness loss for some games (video playback)
gain: reduces graphics load
