Yes, it looks like a gold mind of information but at the moment it is |
45 |
beyond my comprehension especially that I'm looking for quick |
46 |
verification. |
47 |
I'll settle for a simple solution, disable BIOS Network Controller, put |
48 |
another network card on a PCI bus (making sure they are on a different |
49 |
IRQ) and try to re-emerge kde. If it will compile without any problem |
50 |
it would mean I've solved the problem. |
51 |
|
52 |
Another problem with that ASUS A8V motherboard is that they put all |
53 |
additional USB (above 4) on the same IRQ as Sata Controller and Network |
54 |
Controller. |
55 |
This is very bad design, having high demanding resources on the same |
56 |
IRQ. |
57 |
In addition they put Floppy Controller on a separate IRQ 6 without |
58 |
ability to re-assign it. So one IRQ 6 is waisted if you don't have |
59 |
floppy drive. |
