Changes in 1.3.pre1 (November 17, 2001):
|
||||
- Add new log action "ask", as in these example bochsrc lines:
|
||||
- networking works on Windows and Linux platforms
|
||||
- emulated cdrom can now read from ISO image files, on any platform.
|
||||
- new PIT model by Greg Alexander which is much more complete than the
|
||||
old one. The new PIT is used by default, but you can switch back to
|
||||
the old one if you configure with --disable-new-pit.
|
||||
(PIT = 8254 programmable interrupt timer)
|
||||
- new configuration menus by Bryce Denney, which allow you to change any
|
||||
bochsrc option using text menus, then save the configuration into
|
||||
a new bochsrc file for later use. You can disable the new code using
|
||||
configure --disable-control-panel. Also you can use the command
|
||||
line arguments -nocp or -nocontrolpanel. Also, there is a new
|
||||
"Config" button on the GUI that allows limited changes to the
|
||||
configuration at runtime, such as changing the floppy disk.
|
||||
- add docbook documentation directory in the sources under doc/docbook.
|
||||
The transition from HTML to docbook documentation is still in progress.
|
||||
- Add new log action "ask", as shown in these example bochsrc lines:
|
||||
panic: action=ask
|
||||
error: action=ask
|
||||
When an event occurs which is set to "ask", you get a beep and message

- PCI support improved by Volker Ruppert, including BIOS changes. Still
|

not complete.
|

- the ROM BIOS now detects nonbootable disks, and prints a message on the
|

console. Thanks to Cliff Hones for a patch that included the console
|

display code, and Barry Allard who helped with checking the boot
|

- floppy controller returns a proper error response if you try to write

a read-only disk image. For systems such as DOS that actually use the BIOS

services, it was also necessary to add code in int13_diskette_function to

recognize a write-protected error and return the correct error status code

(AH=3, Carry Set).

- LBA support added for hard disks. (Not tested very much.)

- add dependencies to makefiles

Bochs simulation time starts to run faster than real time. This helps to

keep the Bochs clock in sync with the real clock when the CPU is mostly

|

- in task_switch when it tried to ensure that the old TSS was paged in,

- add docbook documentation directory in the sources under doc/docbook.

The transition from HTML to docbook documentation is still in progress.
|

- updated the instrumentation code, and added a working example. To try
|

it, configure --enable-instrumentation=instrument/example1. Then when
|

you run bochs, you will get one line for each instruction PC and for

each I/O access in a new file called bxevent.txt.

- set a bit in the CMOS that says the processor has an FPU. This is

from patch [ #455006 ] Device byte is not initialized aptly.
|
||||
Author did not leave their name.
|

- add logging code to the "null ethernet" which does not require host OS

support. All this does is print the outgoing packets from the guest OS.

Debugger:
|

- do a vga update whenever you print a debugger prompt.
|
||||
- added debugger command "info fpu" that prints the FPU registers. If you
|

do "info all" you get cpu and fpu registers.
|

- added debugger command "info ne2k" which prints all the registers

of the NE2000 model

- fixed problems in which bochs compiled with debugger measured time

Amiga MorphOS platform notes:

Amiga MorphOS specific:
|

- Bochs now compiles and works on Amiga MorphOS. Configure with

||||
screenmode options. The Amiga MorphsOS is written and maintained by

Nicholai Benalal <nicholai@chello.se>.

BeOS specific:

- Bochs compiles and works on BeOS. Configure with --with-beos.

Bernd Thorsten Korz <bernd.korz@insidebeos.de> maintains the BeOS port.

MacOS X specific:

- Bochs now compiles and works on MacOS X. Configure with --with-carbon.

Emmanuel Mailliard <e.rsz@libertysurf.fr> ported the Macintosh code to the

Carbon API.
