I've tried it before, and it failed. There is also a Weiyan ph101, is ngff, efi64 and efi32bios, can brush each other, also failed.
I did research - I checked if ISO images of systems WinXP SP2, WinXP SP3 and Vista Beta 5219 support eMMC. It looks like WinXP SP3 and Vista 5219 supports eMMC. There are such drivers in ISO images: Code: sdbus.inf, sdbus.sys, sdhcinst.dll, sffdisk.inf, sffdisk.sys, sffp_mmc.sys, sffp_sd.sys in WinXP SP2 - version 6.0.4069.1 but there is no sffp_mmc.sys file in WinXP SP3 - version 6.0.4069.5512 in Vista 5219 - version 6.0.5219.0 In SP3 & 5219 sffdisk.inf section [Generic] contains both SD\CLASS_STORAGE and SD\CLASS_MMC entries: Code: [Generic] %GenericSDMemoryCard.DeviceDesc%=sdstorage_Install,SD\CLASS_STORAGE %GenericMmcMemoryCard.DeviceDesc%=mmcstorage_Install,SD\CLASS_MMC In SP2 sffdisk.inf section [Generic] contains only SD\CLASS_STORAGE entry: Code: [Generic] %GenericSDMemoryCard.DeviceDesc%=sdstorage_Install,SD\CLASS_STORAGE Maybe to work eMMC simply I only need use this drivers from SP3 or 5219, add HW ID ACPI\VEN_8086&DEV_0F14 in the sdbus.inf file and sysprep.inf: Code: ACPI\VEN_8086&DEV_0F14=%SYSTEMDRIVE%\Drivers\5_eMMC\sdbus.inf SD\CLASS_MMC=%SYSTEMDRIVE%\Drivers\5_eMMC\sffdisk.inf Maybe no need ported drivers?
@jonathan_hzs Bacause QEMU UEFI internal shell not support this loader. Try bootcut.efi (but in my qemu still not work): boot.efi and bootcut.efi works OK in VMware UEFI shell.
Can this method or instructions also work on older computers? I mean those that use BIOS (not UEFI). Is Windows XP SP3 + Updates PosReady 2009 Compatible? Sorry if this question seems silly.
