Hi, Thanks for the advice. I started playing around with accessing the 8253. Mainly I was trying to see if I could debug what the problem was for streaming ADC data. I am guessing that the counters never get set correctly on my hardware. I am not sure if that is an oddity with the CPU/backplane or the PCI-1200 card. Everything else appears to work fine. When I do loads and reads from the 8253 registers I get intermittent results. Oddly enough inb doesn't seem to read the counter data, however, readb does. writeb will not update the data, but outb does, sometimes. By the way, in 8253.h, the inline function i8254_read, don't you want to or the byte data with 0x30 so that you get a 2 byte read back to back? Any ideas you might shed on how I can get at this problem would be welcome too. Again, thank you for the help you have already provided. Regards Chris
