To make life easier you may want to download the Flash Image GUI app from the market. Yes, it's $.99 but it will save you so much hastle with getting ROMs installed with hboot 1.5. As you may or may not know, when you flash a ROM from recovery is doesn't install the kernel as it can't access the proper partitions without s-off. The Flash Image GUI app will preflash the kernel for you (from the original ROM zip file) and get that part done for you prior to flashing the ROM. Works like a charm! You can also use it to install other recovery images. It's worth every penny, I promise you that, especially if you like to flash ROMs a lot (like me!).
