Parport1 Error

george_114 — Mon, 03 Nov 2003 22:17:23 GMT

I have configured parport1 on my redhat server machine.The following steps that i have done:
#vi /etc/modules.conf and added the following sintax:
option parport_pc io=0x378,0xbc00 irq=7,auto
#reboot
After that i have done:
#dmesg > /tmp/a
#grep parport /tmp/a
parport 0xbc00 (WARNING):CTR:wrote 0x0c,read 0x0d
parport 0xbc00 (WARNING): DATA:wrote 0xaa, read 0x00
parport 0xbc00 : Your gave this address, but there is probably no parallel port there !
parport1:PC-Style at 0xbc00 [PCSYP,TRISTATE,EPP]
ohci1394:pci_module_init failed

Any body know why this happens ???
Thanks in advance ......

I would be interested to see if you still get these errors if you removed the options from /etc/modules completely. You shouldn't need to specify these unless you have peculiar hardware.

So lets get this straight, you've got a server, and you're adding a second LPT port.

I have issues with the second address.

By normal standards, the first LPT port is at 0x378 (yay), and the 2nd is at 0x278, and a 3rd is at 0x3bc.

Verify the address you're using for your 2nd parallel port.
