SCOTTSDALE, Ariz., June 10 2004 — Mobility Electronics, Inc. (Nasdaq/NMS: MOBE), a leading provider of innovative portable computing solutions for the mobile electronics device user, announced today it has added support for the Red Hat® Linux ™ 9 operating system in its MAGMA™ CardBus-to-PCI Expansion Systems.

In the past, Mobility Electronics’ MAGMA operating system support for laptop computers has backed the Windows® and Mac OS® environments. Adding Red Hat Linux to the list of supported operating systems will allow Mobility Electronics to support a substantial mobile user base with a new method to add more PCI slots to their Linux-based laptop computers.

Mobility Electronics’ MAGMA-branded line of patented PCI expansion products provides a cost effective method to add 1, 2, or 4 full-length PCI slots to laptop computers. This allows Linux-based laptop computer users to take advantage of Mobility Electronics’ line of portable PCI expansion products. The CardBus-to-PCI Expansion solution provides a method to use standard PCI cards through the CardBus (PC card) slot available on most laptop computers in the market today.

“We are providing Red Hat Linux support in response to customer requests to use our CardBus-to-PCI Expansion products with laptop computers running under the Linux operating system,” said Charlie Mollo, chief executive officer of Mobility Electronics. “This latest addition completes our Linux support offerings, making it available to the entire PCI expansion user base, including desktop and laptop users.”

Red Hat Linux 9 support is readily available to the entire MAGMA PCI Expansion product line. A driver is required for the CardBus-to-PCI Expansion System and can be downloaded at http://www.mobl.com/expansion/support/support_utils.htm. No driver is required for PCI-to-PCI Expansion Systems to be recognized by the host machine. The computer BIOS software recognizes and configures the MAGMA PCI Expansion System automatically.
