+x86 f1 opcode hangs qemu
+
+I have qemu installed and running in linux and windows
+in linux i execute the following simple code in real mode of cpu in my vm
+90 nop
+90 nop
+90 nop
+f1         ;this should conjure up my interrupt handler from ivt int 1
+--------- end of code ----
+it works properly in vbox,qemu linux,and even in my boot loder
+on a real platform
+   it doeas not work fine in windows 10 (32 bit efi) based qemu
+---
+all of the below was retyped there may be typo
+so onwards to the flawed software 
+********** for qemu-system-x86_64.exe **********
+info version 
+4.2.0v4.2.0.11797-g2890edc853-dirty
+********** for qemu-system-i386.exe **********
+info version 
+4.2.0v4.2.0.11797-g2890edc853-dirty
+***********************************************
+my startup code is
+"d:\programs\qemu\qemu-system-x86_64.exe" -m 16M -boot a -fda "d:\floppy.img" -cpu Nehalem -machine pc
+---
+also same flaw if i change above section to
+"d:\programs\qemu\qemu-system-i386.exe"
