I found exactly the same. Neither our office DELL nor their optiplex mini-tower worked. With the Elite listerboard they even fail to power up due to the high power consumption of the card. I found an old digital that at least can boot with the listercard, but I haven't yet tried to hook it up. I'll give it one more go.

I tried to use a newer DELL and there was no way to lock out the IRQ which the XL data acquisition PCB requires. This Dell always asigned the needed IRQ to a universal serial port and it could not be made to work as the acquisition computer on the XL. As vendors try to make their systems more plug and play they become more difficult to manually configure. Be sure the system BIOS allows you to block out these hardware settings for the ISA bus. gary Gary Durack University of Illinois Biotechnology Center voice (217) 244-0559 fax (217) 244-0466 durack@uiuc.edu http://www.life.uiuc.edu/biotech
