I've been doing battle with an old Compaq Contura 4/25 recently. The parallel port behaves oddly. No diagnostic can pick it up, however I got it working with Laplink 5 after some experimenting.
In CMOS setup I have the options
Now the only way I have got it working is to set it to LPT2 IRQ7 in CMOS and then in Laplink tell it it is LPT1 at address 378h, using polling, and although it can't self test and resetting the port sometimes locks up the computer, quitting out of the setup and attempting a connection works fine. I have a suspicion that when set to LPT1 in CMOS the port address will be 3BC, but laplink didn't seem to like that.
To all other diagnostics and system information programs I run, the port appears completely absent.
So, I am wondering if this is a "feature" of this computer, or the port is broken somehow. Compaq seems to provide some parallel port utilities and a BIOS flash for later conturas, however, nothing seems to be specifically for the 4/25. In fact it worries me that some of their BIOSes seem to indicate compatibility at the bottom of the info page with more models than they could possibly work with. If anyone knows of a ROMpaq for this sytem I'd appreciate it greatly if it fixes this parallel port prob or adds a user definable HDD type.
Also at the moment I am particularly wondering if this is a "feature" whether Linux is known to have problems with it. As I would much like to network under Slackware with a PLIP cable.
thanks much in advance for your responses,
