Re: how to install a second or third hard drive
I am using a SCSI card. I also have a Rev. 2 motherboard.
Just wondering if a non-root partition should be a or g?

Are you using the built-in ATA controller or a SCSI card? If you're
using the built-in ATA controller, there are some problems with the
Rev. 1 logic boards used on these machines.
From LowEndMac.com (http://www.lowendmac.com/ppc/blue-white-power-
The Rev. 1 board isn't stable with many modern hard drives on the
built-in IDE bus because the controller doesn't support UDMA
(MacOS X does an end run around this problem by disabling UDMA on
the Rev. 1 motherboard).
When buying a blue & white G3, insist on getting a Revision 2
system. The best way to make sure you're getting a Rev. 2
motherboard is the "402" marking on the CMD646 IDE controller chip.
Although this model doesn't support drives larger than 128 GB on
its main 33 MHz drive bus, the 16.7 MHz bus used for the optical
drive supports multi-word DMA 2 and may support larger hard drive.
I have two Rev. 1 logic boards, but I use a very small install of
NetBSD on these machines. It fits a 1GB CF card in an ATA-CF
adapter. It's a firewall, so I run it swapless.
I have mostly forgotten about newfs options, so I can't help you on

I have an Apple Mac B&W running NetBSD 4 that I want to add 2 new

Here is what I did:
dd if=/dev/zero of=/dev/sd1c bs=8k count=1
Command (? for help): P
No partition map exists
Command (? for help): i
Command (? for help): P
Command (? for help): C
First block: 2p
Length in blocks: 2p
Name of partition: data
Type of partition: Apple_UNIX_SVR2
Available partition slices for Apple_UNIX_SVR2:
a root partition
b swap partition
c do not set any bzb bits
g user partition
Other lettered values will create user partitions
Select a slice for default bzb values: g
Command (? for help): w
Writing the map destroys what was there before. Is that okay? [n/
Command (? for help): q
disklabel -e /dev/sd1
I changed partition "a" to "g"
newfs -b 2048 -f 16384 /dev/sd1g
I ran through the same process for drive sd2.
I then did:
mount -rw /dev/sd1g /backup
mount -rw /dev/sd2g /backup/data
I also added these drives to fstab.
As soon as I started writing to /dev/sd2g (the 750GB drive) the
system crashed and when it booted up it was in single user mode.
After removing the 2 new drives from fstab it booted fine. My
questions are, should I not have changed the drive letters in the
disklabels and should I run newfs -b 4096 -f 32768?
