[pmax]. sd driver on r4k000, r4400 pmax?

[Jonathan Stone <kiwi_jonathan%yahoo.com@localhost>]

Has anyone successfully used the "sd" driver on a DECstation 5000/150, /50, or /260?
On either the motherboard "ioasic" SCSI, or with a Turbochannel SCSI card?

I have a 5000/150 (R4000), It's never been able to find disk devices with the "sd" driver.
Not with 9.1, not with a 1.6(?) kernel built in 2020. This machine was in storage for ages.
It's still got a kernel with the ex-4.4BSD "rz" driver, which works just fine. (I'm guessing that's why it has the old kernel)

I just got a 5000/25 (Personal DECstation) to boot and run through sysinst. I installed to a SCSI2SD, so hopefully I can move that to other pmaxes and answer my question,  for the hardware I have. 

In case it matters, I'm using NetBSD-8.2, for the DEFTA FDDI driver.
