Thank for Peter and Wonko.
I used PicoXP boot from CD in VMware ,and virtual machine have C: D:
But I can not find C: D: .It seemed that PicoXP can not load File System?
And I can't understand what Wonko mean?
VMWare can use a (virtual) hardware which is NOT always by default seen in a XP or in any "basic" PE, because a driver for that (peculiar) hardware is missing and needs to be added to the build.
Please note that the needed driver depends on the kind of device you use in your VmWare Virtual MAchine, there are two possibilities, the IDE disk or the SCSI disk.
Make SURE that your VM is using a IDE disk and NOT a SCSI one.

Basically you have THREE choices:
1) try again VmWare after making sure that you are using a IDE disk as (hopefully) the "Standard Dual Channel IDE Controller" driver will work on it
2) use another Virtual Machine (like Qemu) that uses only a "plain" (virtual) IDE adapter which surely works with the "Standard Dual Channel IDE Controller" driver
3) add to the PicoXP the needed driver for the "special" (virtual) hardware VmWare uses when using a SCSI disk (LSI Logic)
