With the new 3.01 and 3.07 version I found a big slowdown booting from USB devices. On my PC it takes more than 2 minutes to load the kernel and the initrd filesystem. Compared with the previous behaviour of syslinux 2.13 with takes only 10 seconds or little more. The BIOS boots in FDD mode (DriveNumber variable is 0). I've also tried to disable the EDD support in the source. But the boot process takes always a long time. I've also a PC which boots in HDD mode (DriveNumber has the highest bit set) and it is also slower, approx 20 seconds compared to the previous 10. I don't understan...

Allow the grub loader to (optionally) support using a GRUB menu file. For example chain fs grub=stage2,grub.conf will load GRUB's stage2 and pass the (absolute) path to the file "grub.conf" in the Syslinux filesystem to GRUB's stage2. The path is passed to stage2 in GRUB's device/partition syntax (eg, "(hd0,1)/foo"). Note that we don't check whether the
