>Description:
Trying to boot either kernel or miniroot for installation, kernel
reports presence of hard disk (Seagate 1.3gb/EIDE) and CD-ROM
(Mitsumi 4 speed/IDE), then informs of 7 other SCSI devices reporting
nonsensical geometry (mode sense 4).

Then reports "10 views configured", and halts. Caps-lock responds
by lighting up upon press, so maybe it's not completely dead.

(System is A1200 68030/MMU/25MHz, 4MB RAM, no FPU, on a GVP card)
>How-To-Repeat:
Simply boot the miniroot from the swap fs, or boot the kernel with loadbsd.

State-Changed-When: Tue Aug 3 06:07:56 PDT 1999 
State-Changed-Why:  
From the NetBSD-1.4 Install document, e.g. 
ftp://ftp.de.NetBSD.ORG/pub/NetBSD/NetBSD-1.4/amiga/INSTALL.html 

NetBSD/amiga System Requirements and Supported Devices 
[...] 
The minimal configuration requires 6M of RAM (not including CHIPMEM!) 
and about 75M of disk space.  

So you should expect that it doesn't currently work on your 4 MB machine. 

This is a known, but not analyzed problem. As netBSD/Amiga feels much 
faster with 8 MB than 6 MB; MUCH faster with 12 MB than with 8 MB, and 
even MUCH faster with 16 MB than with 12 MB, this is not the most 
urgent bug on our list...

 Rob, Petri:

 there is a reason I didn't close the PR.

 NetBSD/Amiga not booting at all on a <6MB machine (for todays kernel sizes
 for <8MB) is the result of a bug, or more probable of the general misdesign,
 in the pmap module. Basically, pmap needs to be rewritten, and this won't
 happen fast, but when it is rewritten, a 4 MB amiga should be able to
 startup a small enough kernel and, while not to run it, at least to crawl it.

 Thats the reason that PR is still suspended and not closed.
