- Common hdimage code, lowlevel cdrom code and the classes for the Bochs "own"
image modes (e.g. flat, sparse, growing") are now a part of the Bochs core.
- All classes for image modes present in separate files are now built as
plugins with the same self register mechanism as network, sound and usb
modules. Defined new plugin type PLUGTYPE_HDIMAGE.
- Temporarily disabled the base image format detection of the undoable/volatile
modes for the "external" modes in the plugins case.
- TODO: Bochs should know about all of the available plugins and their
capabilities right after startup, but before the configuration stage.
- 'flat' mode: disk image size must be multiple of sector size.
- 'concat' mode: each disk image size and lseek() offset must be multiple of
sector size.
- 'sparse' mode: page size and lseek() offset must be multiple of sector size.
- TODO: 'growing', 'undoable' and 'volatile' mode: redolog_t class is still
based on 512-byte blocks.
- TODO: 'vbox', 'vmware3', 'vmware4', 'vpc' and 'vvfat' mode have a builtin
geometry. If other sector sizes are supported, it should be handled correctly.
- harddrv code now reports current sector size, but still panics for now.
- TODO: harrdrv and USB disk code, bximage, BIOS.
- Create a file with image name plus extension ".lock" if an image is opened
in read/write mode. This file will be deleted after closing the image.
- Check for a lock file before opening an image and fail if it exists.
- Check for a lock file before creating a undoable/volatile redolog file and
fail if it exists.
"fatal". It can be used for all cases when there is no workaroud present to
avoid application crash or incorrect simulation behaviour. As a first step now
using BX_FATAL() for some data structure size and bit field errors.
sector transfers (buffer pointer update was missing). Multiple sectors transfers
could for the USB disk emulation and for image conversion with bximage.
creation, conversion and rodolog commit. Image creation support is not
present yet and the executable has not been added to standard compile yet.
TODO #1: add floppy and hard disk image creation support (from bximage.c)
TODO #2: implement support for conversion to vmware and vpc formats
TODO #3: add MSVC (nmake and workspace) support
These hdimage modes are now supported: flat, sparse, growing, vmware3, vmware4
und vpc. The image mode is auto-detected, so no change of configuration syntax
is necessary (TODO: documentation update). Example:
ata0-master: type=disk, mode=volatile, path=vmware4-test.img
