Bug Description

QEMU version: 1.6.90.0 from 2013 11 16
Host OS: Windows XP SP3 x86
Host machine: 3.2 GHz AMD Athlon 64 dual core processor, 4 GB DDR II (3.2 seen by the OS) memory
Guest OS: Grub4Dos boot manager menu
Problem: when I use "qemu-system-i386.exe -drive file=\\.\PhysicalDrive1,if=ide,index=0,media=disk,snapshot=off -m 512" it boots twice as slow than the 0.15.1.0 version.
