First, a bit of history... I own an VAX 730, with a DMF32 and a DZ11 both installed. (recived it that way...). I want to remove the DZ11, because I have no use for 16 ports, 8 is fine for me (and I want to install the DZ11 in my PDP-11/34a). I removed the DZ11 and replaced it with the NPG card, and booted the VAX. The DMF32 used to show up as devices TXA0-7, and the DZ11 was TTA0-7 (I might have these reversed, but you get the idea:-) With the DZ11 gone and the DMF32 in its same slot, now I have -no- additional ports! $ SHOW DEVICE shows the disk drives, and the operators console, but no DMF32... I tried running SYSGEN and doing an AUTOCONFIG ALL/SELECT=(TT,TX) but even then that didnt install the DMF32. Ok fine. I know the TXDRIVER.EXE is loaded, because I can see it using the SHOW command of SYSGEN. The thing is, there is no address or anything for it. What I need to know is if I need to reconfigure anything (such as the CSR and whatever) to get it back again. And if so, how do I go about this? Ive never changed any of these setting before, and dont want to do it because I dont know how!! Can anyone help? Or perhaps a manual on the DMF32 to give me direction? Thanx in advance Billy D'Augustine

address switches on the module. Howeever, on VAXes, the VAX auto-sizes
and assign both the CSR address and the interrupt vector according to
some rules. Since you removed the DZ11, now the VAX will expect the
DMF32 to be at a different address and vector. Since you did not
change the address and vector of the DMF32, now the VAX would not
recognize it as a DMF32, probably thinks it is a DZ11 instead. Therefore
instead of getting 8 txa ports, now you only getting one tta port.
To find out what the Vax expect the address and vector to be, do the
following under sysgen:
SYSGEN> config
DEVICE> DMF32,1 ;telling system you have one DMF32
;now hit a control-Z
Now system will present out a list of CSR address and vector
address. This is NOT what the module is set up right now. This is
what VMS expects the address to be in order to recognize it as being a
DMF32. Next you have to find the DMF32 user's guide and set the on
board switches accordingly. Please send me mail to tell me how you do.
