Current and planned Board Support 6.1 Xycom XVME655 Pentium VMEbus Board 6.2 XyCom XVME656 Pentium VMEBus Board 6.3 Dynatem DPC1-0367 6.4 SBS/Or Computer VP7 6.5 DY4 179, A Power PC board 6.6 Planned Board Support 7. Conclusion 8. FAQ 8.1 The Shell utilities return a bunch of stars (*) when I access a board I know is there. What gives? 8.2 The Shell utilities still return a bunch of stars (*) when I access a board I know is there. Now what? 8.3 The Shell utilities still return a bunch of stars (*) when I access a board I know is there. HELP? 8.4 How does VMELinux handle interrupts? 8.5 I have RedHat 5.1 and can't get VMELinux programs to compile. 8.6 I have RedHat 6.x so I assume the above issue is fixed. Right?
