src/sys/arch/i386/stand/lib: biosdisk.c exec.c libi386.h pcio.c vbe.c
Log Message:
Add wait_sec() which uses BIOS function call INT 1Ah/AH=00h (GET SYSTEMTIME)
and use it for large delays (in seconds) instead of delay() that uses
INT 15h/AH=86h (WAIT) in microsecond because the latter one can't provide
precise delays on emulators.
Fixes PR port-i386/43156 (NetBSD bootloader countdown runs at 1/20 speed
in qemu 0.12).
No particular comments on the PR and port-i...@.
