CD Shell: Change Log

Change Log

CD Shell 2.1.6

April 17, 2005

changed behavior of display.message to interpret a backslash as a single-character quote if not recognized as an escape sequence (suggested by Erwin Veermans of the Ultimate Boot CD project)
isolinux patches as suggested by Charles Appel of the Ultimage Boot CD project
- patched a bug in isolinux that would display some garbage characters when loading a kernel (just before 'Ready')
- changed behavior for the display command to not show a splash screen unless isolinux was invoked with an empty command line
incorporated changes to chooser script
- allow onEscape action when user quits the menu
- allow per-item exececute-on-select commands
- fixed a bug where text in the message window wasn't being updated correctly

CD Shell 2.1.5

March 1, 2005

fixed a bug where isolinux wouldn't find /boot/modules/isolinux as its home directory. Now you can place isolinux.cfg there and it will actually work.
fixed a major bug in display.init (.check_vbe) that would do very bad things
diskemu no longer supports up to four floppy drives (2 physical + 2 emulated), now supports only two drives (0, 1, or 2 emulated, the rest physical)
made cdrom emulation more robust
finished implementing Chooser script
added case-sensitive file system mode for ISO9660:1999 format discs. If CD Shell detects that your disc is in this format (mkisofs: "-iso-level 4") all file names will be treated as case-sensitive.
reimplemented macrousage command as $macrosDefined macro
fixed a bug in the no-emulation mode of diskemu's iso emulator
implemented "return here" command
updated isolinux module to HPA's 3.07 version
fixed a bug that prevented stepping through the startup sequence in the loader
fixed a bug that would cause corruption if you executed "set blah = "
workaround for BIOS anomaly: don't reset overscan if user never changed it

CD Shell 2.1.4

October 12, 2004

CD Shell 2.1.3

September 3, 2004

CD Shell 2.1.2

September 1, 2004

CD Shell 2.1.1

September 1, 2004

fixed bug in diskemu causing "Enter name of command interpreter>" prompt on bootable MS-DOS floppy images
added proper iso emulation into core via int 0x13 hook (makes module programming easier)
fixed bug where extended keystrokes (eg. F11, F12) were being discarded
isolinux modified to use /boot/modules/isolinux as default directory for isolinux files, rather than /boot. You can still use /isolinux as well
fixed Ranish Partition Manager module
moved part.exe and memdisk into subfolders of modules folder
changes to display.shutdown: more thorough cleaning of display
memtest module created, memtest command added
hotkey module removed from main build and documentation (who uses this anyways?)
optimized macro module to not allocate so much memory for user-defined macros

CD Shell 2.1.0b

August 18, 2004

updated isolinux module to HPA's version 2.11
possible bugfix in isolinux module (getonesec/getlinsec)
Syntax highlighting definition files added to /tools folder
- EditPlus definitions courtesy of DoctorXP
- TextPad definitions courtesy yours truly
fixed a bug where flags were being hosed after a restart command
length[] function added to basic.csm (calculate string length)
CD Shell major.minor version changed to 2.1
module format changed to version M.4
period now allowed as part of a macro name
commandBuffer in module header no longer points to the real command buffer, but a new buffer dedicated to the modules' use
changes to command processing engine:
- commands are now parsed for macros from right to left
- macros can now be written with in parenthesis: $(macro_name)
- call/goto/return are now significantly faster, since macros aren't parsed during the label scan
eval.md5 now works! It produces real md5 hashes instead of pseudo-random garbage. :P
re-enabled MD5 macro
updated Paul Wabno's script to use MD5 hash function
fixed a bug in cdshw.com that caused keyboard input to get mangled

April 30, 2004

major rewrite of diskemu module finished
- some bugs were fixed, probably some more were added, so still beta
- now emulates more than one floppy
