- The config.in file of the 0.99 kernel sources contains a small typing error:
- I think CONFIG_AUTOIRQ should be CONFIG_AUTO_IRQ, otherwise this stuff will
- never be included (Linus, do you hear me?).
-
- Second, NEW_INTERRUPT_ROUTINE is #undef'ed in kernel/chr_drv/serial.c by
- default, is this intended? (The comments state that it should be okay for
- most people!?)
-
- I came across these because I have two simple serial cards which I want to
- use simultaneously:
-
- As far as I read from recent news, these cannot share the same IRQ-lines.
- The last weeks there have been some postings regarding multiport cards,
- but with a little soldering, you can use IRQ's 10 to 12 with every
- off-the-shelve short (8 bit) card! I read about this in the German
- computer magazine c't (jan '93) and intend to try that for Linux.
- You "just" have to disconnect the IRQ3/4 lines of one card and connect
- them to the pins D3 and D4 of the upper part of the slot connector, which
- drive the IRQ10 and IRQ11 lines (i.e.).
- To do this, you only need a card which fits into the 16-bit-part of the
- AT-bus-slot and a few inches of wire (I will recycle an old CGA card...).
- The only problem might be to find the IRQ lines on the serial card, but most
- of them have jumpers to set the IRQ's. These can be left open and will be
- the points where the new connector has to be attached to.
-
- Of course this should ONLY be done if you are not afraid of
- hardware-hacking and know what you are doing!!!
