Dear Shao, The disk image is not compressed. The size is about 111M. Actual, the WINPE itself is loaded correctly(winpe boot progress show it) but the system could not startup. I use the MEMDISK version 3.82. MEMDISK is loaded first in gPXE, then the initrd. Further, I have notice that MEMDISK shows the disk image is loaded in different address: It is at 0x8f800000, length 0x06dd1c00 with gPXE -> MEMDISK is and 0x8f800000, length 0x06dd1c00 with gPXE -> PXELINUX -> MEMDISK. The new int13 address is at 8fc0000a and 9340000a respectively. So we could see the new int13 address 8fc0000a is obviously in the range of 0x8f800000, length 0x06dd1c00 which should be the disk image in the gPXE -> MEMDISK case. But the new int13 address is out of the range of disk image in the gPXE -> PXELINUX -> MEMDISK case. Is this a potential problem the int13 address in the range of disk image? Thanks!
