hello list, searching information that could help me solve the |
2 |
problem of my old HP laserjet 1100 printing too slow, i found |
3 |
something about dma and parallel port. |
4 |
|
5 |
i activated ECP on the bios, the address of the port is 378, irq 7 |
6 |
and dma 3. but dma is not activated when booting: |
7 |
|
8 |
lj@acme ~ $ dmesg | grep parp |
9 |
Kernel command line: root=/dev/hda1 vga=773 ro parport=0x378,7,3 |
10 |
parport0: PC-style at 0x378 (0x778), irq 7 [PCSPP(,...)] |
11 |
lp0: using parport0 (interrupt-driven) |
12 |
|
13 |
lj@acme ~ $ cat /proc/sys/dev/parport/parport0/dma |
14 |
-1 |
15 |
|
16 |
i have the drivers compiled in the kernel, not as modules. i added this |
17 |
line in menu.lst: |
18 |
|
19 |
kernel /boot/vmlinuz root=/dev/hda1 vga=773 ro parport=0x378,7,3 |
20 |
|
21 |
not sure about the syntax, i couldn't find anything in the grub |
22 |
documentation about passing kernel parameters. anyway, i get no dma on |
23 |
parport0. |
24 |
|
25 |
i have an oldish soyo kt333 motherboard, and i tried this with |
26 |
different recent kernels (2.6.23 and 24) |
27 |
|
28 |
any help greatly appreciated. |
