The size of the chip giant's investment in eSoft wasn't disclosed when the deal was announced in November, but it was enough to send eSoft's stock rocketing upward. The $3 million figure was released in a Securities and Exchange Commission filing today.
The investment is one of several Intel has made in companies using the open-source Linux software. Intel also has invested in Red Hat, SuSE, TurboLinux and VA Linux Systems.
eSoft makes server "appliances," computers designed to handle specific tasks on a network more easily, more cheaply or more quickly than their general-purpose brethren.
Cobalt Networks, another manufacturer of Linux-based server appliances, raised $110 million in its IPO in November. CyberNet Systems, which writes software for Linux-based server appliances, plans to go public as soon as March.
