PM_haveBIOSAccess
Determines if access to the real mode BIOS is available
Declaration
ibool PMAPI PM_haveBIOSAccess(void)
Prototype In
pmapi.h
Return Value
True if the system provides BIOS access, false if not.
Description
This function is used to determine if the operating system can provide access to the real mode BIOS or not. Many operating systems can provide full access (DOS, Windows 9x, Linux), others can provide limited access (OS/2) while other still provide no access (Windows NT/2000/XP, QNX etc).
If you need to call the PM_int86 functions, you can first call this function to determine if the BIOS access is available or not. If this function returns false, do not call the PM_int86 functions!
