Subject: Fw: 16-bit bootloader support?
Date: Thu, 8 Oct 2009 23:17:04 +0000 (GMT) [thread overview]
Message-ID: <219513.91960.qm@web37103.mail.mud.yahoo.com> (raw)
I'm sorry for the top-down mail but Yahoo! Mail is gay. No, I don't mean virtual 8086 mode, I mean the 16-bit protected mode - which is 16-bit and not 32-bit. Protected mode was introduced on the Intel 80286 which was still a 16-bit CPU. Protected mode was later extended for 32-bit allowing of course for backward compatibility. Windows 3.1 is a good example of an OS capable of handling 16-bit pmode.
It's not legacy code I'm talking about.
Cheers,
Bogdan

Which mode do you mean?
protected mode=32-bit mode
You may mean vm8086 mode but it's meant only for compatibility purposes.
As such it's an OS responsibility to set it up when executing legacy code
