92c6120d7a Some work on the seek latency feature
- rewrite of the logical sector handling code to make seek latency support possible
- implemented variable HD seek latency for seek and read commands
- TODO #1: CD-ROM seek command returns status immediately, but it clears the DSC bit
  and sets it at completion. Device should not accept ATAPI commands until DSC is set.
- TODO #2: clean up the seek latency code

54138f294e Some work on the ATA/ATAPI seek feature and related changes
- now using the more accurate name "seek latency"
- fixed CD-ROM LBA address range checks and renamed limit to "max_lba"
- make the latency for CD-ROM access variable depending on the distance between
  current and new block address, Maximum value should only occur at first access
  or after media change.
- TODO: make hard disk seek timing variable, too.
- still TODO: seek latency for USB drives (requires asynchronus packet support).

78509d637b Implemented seek delay for hard disk and CD-ROM PIO read commands using fixed
values for the average access time (hd: 5 msec / cd: 80 msec). Hard disk write
and DMA mode commands are not affected yet.

f3a6fbd235 Simplified setup of special runtime menus / dialogs
- If the runtime flag of a bx_list_c object is set, all it's items are set up
  as runtime options.
- Set the runtime parameter for all top-level runtime-only lists. Setting up
  each single parameter is no longer needed.

b452803be5 Preparing lowlevel cdrom rewrite
- use #if BX_SUPPORT_CDROM instead of #ifdef LOWLEVEL_CDROM
- devices with cdrom support now use the base class cdrom_base_c
- cdrom count variable moved to cdrom.cc
- cdrom_misc.cc: don't use ioctl's for ISO files

cc56245407 started implementing the i430FX chipset
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets

9ee5a77747 - started implementation of sav/restore support for hard disk images using a
dummy parameter and it's save/restore handlers. Currently only the save
  support is implemented and the specific save function is only written for
  flat mode images (copies whole disk image file to the save/restore folder).
- TODO #1: implement save function for the other disk image modes
- TODO #2: add restore support (replace disk image file with the one from the
           save/restore folder)

8bb206ccdf - added special flag for dependent lists
- bx_list_c: don't accept duplicate param names in list (except dependent lists
  and special menus)
- added BX_PANIC for malloc() failure

b130bf671b - initial "log action by device" implementation added (TODO: check for
invalid module names, save log actions to bochsrc)
- added new member 'name' to the logfunctions class for the case the prefix
  is too short. Added to some devices with longer names.

0b2bec6752 - implemented "auto-off" timer for the status bar LEDs that replaces the
existing "iolight timer" code in the hard drive code. If an LED is registered
  with the "auto-off" flag, the device only needs to turn on the LED to indicate
  data transfer. The LED timer in the gui code turns it off after 0.5 seconds if
  it is not actived by another transfer. Added this feature to all network
  devices.
- TODO #1: implement this feature in the USB host controllers
- TODO #2: the unused timer in the hard drive code could be used for the
  emulation of seek functions

3029d55f4a - hdimage 'flat' mode: added support for Linux block devices (part of SF patch #3412431)
- hdimage: renamed 'sectors' to 'spt' (same as the config parameter)
- harddrv: fixed info message

67db6ee123 - disk geometry detection and check code rewritten:
* if the image provides a geometry, always use it.
  * if the cylinder value is set to 0 and the image supports autodetection,
    calculate the cylinder value from disk size, sectors and heads.
  * in all other cases the specified geometry is used.
  * a panic only occurs if the image size is too small for the geometry.
  * extra data past the end of the disk now causes an info message.
- TODO #1: 'flat' mode hdimage: read disk size of raw devices on Linux
- TODO #2: 'flat' mode hdimage: use geometry from MBR on image if present

c8d2f60225 - added runtime config handler for the ATAPI cdrom code. Now the media change is handled after both
parameters (path + status) have been set. TODO: implement this feature for the floppy, too.
- call update_drive_status_buttons() from update_runtime_options() to reduce the number of calls.
  Now call update_runtime_options() from the gui floppy / cdrom handlers after closing dialog.

5014eed268 - link lowlevel cdrom support with the hdimage plugin instead of harddrv and usb_common. This fixes
duplicate log prefixes on Windows if both IDE and USB cdroms are used in plugin mode. Windows also
  requires the cdrom base class and the init_cdrom() method to link and work correctly.
