ISA-only attachments would be a good place to start. My quick glance shows this would be le(4), aha(4), cm(4), mse(4), and joy(4). There's maybe half a dozen EISA-only drivers in the tree that I was planning on retiring in 12, along with EISA. Likewise with the MCA attachments. I know that ed, ep, ex, sn, fe and cs PC Card attachments still work, or did fairly recently. All of those also have ISA attachments. I have no clue if the ISA attachments work, though I still have some ISA systems, I got rid of all my SCSI and Network ISA cards some time ago. I had hoped to get all the pnp autoloading code going so we could remove them from GENERIC before the 11 branch, but keep them as modules. I ran out of time. However, there's still time for 12 though. Warner
