class's prefix, NE2K. The real issue is that the ne2k class exists at
configuration time, so it is possible to tell it how to respond to
panics, errors, etc. The packet mover is created after configuration
depending on the setting of bx_options.ne2k.Oethmod, so I cannot
(with major hacks) affect its settings from the configuration interface.
Several packet movers were already set up this way anyway.
certain number of instructions. I use it for performance testing, and it
won't hurt anyone unless they are foolish enough to enable it in config.h.
Of course it is disabled by default!
Some devices already had one. Some I had to add an empty one.
I did a little cleaning of init() methods to make them more uniform
but generally I left them alone.
- I also put these exact diffs into a patch "patch.iodev-add-reset"
in case I want to revert these changes for some reason, for example
if they break an old patch. It should be deleted after a while.
to "*_ENABLED"
- bx_serial_options for all 4 ports moved into an array com[4]
- serial port com1 is enabled by default
- detection of com2, com3 and com4 config options disabled for now
- new parameter "enabled" added to the serial bochsrc options
- error handling for serial and parallel bochsrc options changed. The unhandled
BX_PANICs are replaced by BX_ERRORs.
- new function bx_write_serial_options() added
- serial destructor restores original terminal settings only when serial port
is enabled and the tty_id is valid
parport1 with the new option "enabled". The old option "enable" only
controlled the output. The parport1 is enabled with no output by default.
Changes:
* bochrc option "enable" replaced by "enabled"
* parport option "Oenable" replaced by "Opresent"
* bx_parport_options par1 and par2 replaced by an array par[2]
* initialize parport1 resources only when enabled
* renamed variable "parport_init_list" to "par_ser_init_list" since it
contains parport and serial options
* documentation and bochsrc updates
- the parport variables "output" and "initmode" now belong to the bx_par_t
structure
- TODO: add parport2 (disabled by default), parport detection in the bios
- PCI configuration space of the host bridge renamed from array[] to pci_conf[]
- new functions load_ROM() and mem_read() for ROM access
- macros for PCI functions defined in bochs.h
more work in the floppy and bios code.
- floppy and cdrom entries in the runtime config menu can be disabled if the
drive wasn't defined in bochsrc or start menu
- floppy variable "initial_status" and cdrom variable "inserted" renamed to
"status"
- unused variable *ips in function build_runtime_options_prompt() disabled
* new floppy type 360k can be used in .bochsrc and the config interface
* media type and geometry can be set for the floppy type
* BIOS changes to make 360k floppy drives work
* bximage can create 360k images now
and works okay with one rom track only. We still have to implement reading
the real TOC on win32.
- in function GetCDCapacity(): type of variable 'buf[8]' must be 'unsigned char'
- in function capacity(): win32 version returned the number of bytes, but it
should return the number of blocks (ASPI blocksize is 2352)
- description of the function capacity() fixed (it always returns blocks)
controller returns an error code until we are able to implement this feature.
- init_send_atapi_command(): don't panic if alloc_length is 0, use byte_count
to set alloc_length instead
- fixed a BX_PANIC message in the io write handler for port 0x1f0
- init(): set the initial status to BX_EJECTED if evaluate_media() fails
- don't modify the DOR when a drive > 1 is selected
- floppy command 'get status' now recognizes the head field
- floppy command 'recalibrate': don't set cylinder to 0 before completion
- floppy command 'sense interupt status' does not clear status register 0
- floppy command 'configure': more detailed BX_DEBUG messages
- floppy command 'read ID' does not modify status register 0
- floppy read/write commands: set the error bit in status register 0 if media
is not present
- better detection of not existing drives in some commands: check the media type
of the selected drive instead of the drive select value
- behaviour of floppy commands 'recalibrate' and 'seek' changed:
* drive is busy in the execution phase, but not the controller
* replaced the panic by setting the error status if drive is not existing
- evaluate_media(): set the media type even if device/file is not present
