To help you all get a handle on my previous question, I got
ahold of 4 900M SMD drives (roughly 8" x 8" x 15") and some 7053 SMD
cards.  I have a Sun 4/260 with a rather lot of crap in it.  I'm
enclosing a list of my slot assignments and the dmesg output of a
typical boot.  I'm having trouble with some sort of interupt conflict
when I plug in the 7053 card 'crazy interupts' came up at least once.

I have:

Slot	Card
====	====
1-----	CPU (takes two slots
2---/
3	8M RAM (might be buying some 32's next month or two)
4	8M RAM
5	8M RAM
6	8M RAM
7	SCSI 0 (goes to internal drives)
8	CG2 (8 bit 1152x900 framebuffer)
9	SCSI 1 (goes to external drives)
10	spare (2nd xd?)
11	xd0 (7053 SMD controller)
12	ie1 (ethernet on motherboard always returns 'dma underrun')

Here is my current dmesg with the 7053 (xd?) card pulled out.
