291FIXME 287Note: HTC Universal support is highly experimental.
292 288
289On the HTC Universal, entirely replacing the Windows installation is not
290supported, instead Poky is booted from an MMC/SD card from Windows. Once Poky
291has booted, Windows is no longer in memory or active but when power is removed,
292the user will be returned to windows and will need to return to Linux from
293there.
294
295Once an MMC/SD card is available it is suggested its split into two partitions,
296one for a program called HaRET which lets you boot Linux from within Windows
297and the second for the rootfs. The HaRET partition should be the first partition
298on the card and be vfat formatted. It doesn't need to be large, just enough for
299HaRET and a kernel (say 5MB max). The rootfs should be ext2 and is usually the
300second partition. The first partition should be vfat so Windows recognises it
301as if it doesn't, it has been known to reformat cards.
302
303On the first partition you need three files:
304
305 * a HaRET binary (version 0.5.1 works well and a working version
306 should be part of the last Poky release)
307 * a kernel renamed to "zImage"
308 * a default.txt which contains:
309
310set kernel "zImage"
311set mtype "855"
312set cmdline "root=/dev/mmcblk0p2 rw console=ttyS0,115200n8 console=tty0 rootdelay=5 fbcon=rotate:1"
313boot2
314
315On the second parition the root file system is extracted as root. A different
316partition layout or other kernel options can be changed in the default.txt file.
317
318When inserted into the device, Windows should see the card and let you browse
319its contents using File Explorer. Running the HaRET binary will present a dialog
320box (maybe after messages warning about running unsigned binaries) where you
321select OK and you should then see Poky boot. Kernel messages can be seen by
322adding psplash=false to the kernel commandline.
