86Box v2.03

Bugfix release.

Changes

This is the list of changes from v2.02:

• Fixed S3 through the plane PIX_TRANS reads.
• Serial port fixes, fixes Windows NT 3.1 1991 builds hanging.
• PCI PIRQ's are now always level when PCI IRQ steering is present, and MIRQ's are now edge/level according to the device that issues them, per the Intel datasheets, fixes annoyingly long wait at POST on PCI Pentium AMI BIOS'es because of secondary IDE.
• Fixed for the array sizes in snd_dbopl.cc.
• PCI TRC hard resets now also reset the AT keyboard controller.
• Numerous serial port bug fixes, now it passes all AMIDIAG tests.
• Converted the serial mouse code to my advanced timer API, which makes the code a bit cleaner (less casts and multiplications with TIMER_USEC).

Prerequisites

86Box requires ROM files in order to operate, which can be downloaded here: https://tinyurl.com/rs20191022 (extract the ZIP file to the same directory as 86Box.exe)

It is also recommended to use the 86Box Manager to manage virtual machines, although it is possible to use the emulator on its own, using the -P/--vmpath command line option.

Which ZIP should I download?

• 86Box is the standard build. Download this if you don't know which one to choose.
• 86Box-Debug includes debug symbols. If you don't need them, you generally don't need to use this build.
• 86Box-Optimized are optimized builds for most modern CPU architectures. See our CPU architectures table to see which build you should download. Using the wrong binary may result in crashes.
