I've just use 1.0 beta 3 to make a XP sp3 install into a SDHC card. I simply follow the steps, format to fat32 with RMPREUSB, then make my XP SP3 setup directory into the SD card. I didn't add anything else(PE, Win7, ubcd etc.), everything is ok. But when I try install XP with it on a IBM Thinkpad R40e, the initialization step was very slow. I mean before I can choose which partition to install the system and agree the EULA, loading the driver and kernel files are very slow. Slow as like it's not working. Is it normal? My SDHC card is capable of 20MB/s reading with big chunk. Is this problem of the usb driver or bios support? On another PC with Sempron 2000+ and 1G ram install, the very similar situation occur. The initialization step the "The setup is inspecting your hardware configuration" step take tooooooo long to complete, the same for the driver and kernel loading stage. When install from CD-rom, it's far more faster. Thank you.
