Works fine for you -- but there are still lots of reports floating about of it being unreliable. So, I'd understand why the driver does not use ECP/DMA by default. But since I know it works for me, I'd like to force it (by giving the appropriate irq and dma parameters in /etc/mod{ules,probe}.conf. It is a little sad to see a 1.2 GHz machine waste 40% of it's cycles for pushing bytes to the parallel port, after all. |
