Phoenix licensed the BIOS to clone makers for $290,000. To reassure customers, the company obtained a $2 million insurance policy from The Hartford against copyright-infringement lawsuits. Phoenix's revenues grew by 100% in 1987, and the company shifted to licensing the BIOS on a per-machine basis instead of a flat fee. Competitors appeared, such as AMI BIOS. Phoenix shipped an IBM PC/AT-compatible BIOS six months after the computer's announcement, and also developed IBM Personal System/2 Micro Channel-compatible BIOS, including the ABIOS, and EISA compatible BIOS during 1988 and 1989.
