I have a 3com 3C501 Ethernet card (MCA bus) but I have misplaced the manual. I would greatly appreciate it if someone could please email me the jumper setting tables for the i/o address and memory address. Thanks, Chris

I think that 3c523 is the Ethernet Card for MicroChannel And that 3c501 is for Normal Bus... isn't it ?? Bye Jose A. Vela A. josevela@mtecv2.mty.itesm.mx

Argh!! Sorry, it _is_ a 3C501, I just screwed up my bus names. If anyone knows the jumper settings for the 3c501 and the matching settings for the setup, or has a 3c501 manual, I'd appreciate the info. Thanks, Chris

I have the same problem, but for the ISA (PC) bus version. To tell the truth, I didn't realize that ther is more than one version of the 3C501.

I have looked at some old documentation I have. It indicates that there may be as many as three cards called the 3c501. Here is some info on all of them. 1. Assembly 0345 (a long card with assy number located towards the middle bottom). dma channel 1 or 3 To select DMA channel 1 both jumpers should be set to connect the left and center pins on JP1 and JP2. This is the factory setting. to select DMA channel 3 both jumpers should fit over the respective center and right pins. interrupt 3 or 5. connect 3 to 4 on JP3 for int 3 connect 4 to 5 on JP3 for int 5. base addr 200-3f0 selected by jp4, jp5, jp6, jp7 and jp8. There are 10 bits in the address numbered 0-9. bits 4, 5, 6, 7 and 8 are controlled by the respective jumpers. for 0 jumper left to center. for 1 jumper center to right. 16 addresses starting at the selected one are used. 2. Assembly 34-0780 (a long card with assy number located in top back corner) dma channel 1,2 or 3 There are two groups of jumpers located by the buss connector oriented vertically. left group of three controls dma req while right group of three controls dma ack. set a jumper to connect (vertically) set 1, 2 or 3 on each. Both req and ack must be the same. Interrupt 2-7 jumpers located to left of the dma jumpers. put one jumper over the labeled pin set to select the int level. iobase address see procedure described above. for 0 connect top to center, for 1 connect lower to center. 3. Assembly 1221 (short card with assy number located on top back corner) See instructions for 34-0780. One or more of the cards seem to have memory address jumpers on them but my manual doesn't mention them. Norm
