If you have cromwell you can flash whatever bios you want on the chip. You probally want to flash it with 4977, its the latest and greatest. Some lites come with 4977 on it, some have cromwell. Some pros have no bios, some have cromwell. There is a cromwell that you use the ozxchip method on and a cromwell that searches for a bios.bin on a disk. If your cromwell searches for a linuxboot.cfg then use the ozxchip method. If not then use the other method.
