But currently we're using the ps/2 kbd interface at the back, where there's also a video interface. Out of curiosity: Are the ISR's really shared, or is it more an "optical" problem? em0 is at irq 30 uhc is at irq 16 The server will be here for at most 1 more week, and is available for tests.... --WjW
