But can you mount CDs if you use the BL2 kernel (which has isofs
built in)?

Because Linux gets its information from the hardware itself, instead
of the BIOS, while DOS relies on the BIOS?

It's funny that you should mention that, as I was just reading a
HOWTO (earlier today) which said that Linux will only support slave
drives if there is also a master drive on the same IDE interface.

I don't think so. You can tell Linux to ignore certain IDE
controllers, but I don't think that is what you want.

Iffy diagnostic test? Or an IRQ conflict which only the test could
detect?

isapnp settings go away after a cold reboot.

AUI? Is that the same as coax?

On another note, I never realized how easy isapnp was until
I installed the latest version of isapnptools on BL2:

1) Install isapnptools
2) pnpdump -rc >/etc/isapnp.conf
3) isapnp /etc/isapnp.conf

The IRQ, DMA, and I/O addresses are displayed if you're using
a console, so you need to run this from a VT, not an xterm.
Here's what I see after inputting these commands:

Board 1 has Identity 35 ff ff ff ff 00 30 32 0d:  CIR3000 Serial No -1 
[checksum 35]
Board 2 has Identity 6d ff ff ff ff f0 00 8c 0e:  CTL00f0 Serial No -1 
[checksum 6d]
CIR3000/-1[0]{CIRRUS LOGIC PnP V34 MODEM}: Port 0x3E8; IRQ12 --- Enabled OK
CTL00f0/-1[0]{Audio               }: Ports 0x220 0x330 0x388; IRQ5 DMA1 DMA3 
--- Enabled OK
CTL00f0/-1[1]{Game                }: Port 0x201; --- Enabled OK

Now, to activate my Vibra16, I do (after insmod of soundcore etc.):

insmod sb io=0x220 irq=5 dma=1

And MPlayer (with OSS) works perfectly. playmidi works after I insmod
opl3 with the address of 0x388. I guess if I used mpuio=0x330 (or
whatever the option is) I could plug in my MIDI keyboard and try that.

For my modem, I just do:

setserial /dev/ttyS2 port 0x3e8 irq 12

And then I can dial up perfectly with any kernel. So it turns out
that I was wrong about isapnp. It is easy, and it works correctly
with the BL kernels.
