I am not sure how it works With NetBSD, but here are some instructions
I found in sunsite when I ran into the same problem installing Linux.
I hope this helps....
The following instructions describe in detail how to create your own
a1 disk so that you can install SLS on a PS/VP. It still requires that
you have access to a machine already running Linux so that you can construct
a special kernel hardcoded for your drive type. Hopefully many of you
can find a friend nearby who can help out.
Maybe someone could post these instructions and their patched kernels for
different drive types to tsx-11.
There should probably be something in the FAQ about this as well.
1) Modify the file /usr/src/linux/include/linux/config.h
Define HD_TYPE with the parameters of your drive. The file config.h has
instructions on how to set HD_TYPE. Many PS/VP's use a Maxtor 7213 212MB
drive, so the changes would look like:
#undef HD_TYPE
#ifdef MAXTOR_7213
#define HD_TYPE { 16,38,683,0,683,8 }
#endif
Note: If you have two floppy drives there are some other patches that you
need to make but I don't know what they are. My friend only had one floppy.
2) Modify the file /usr/src/linux/Makefile
Set ROOT_DEV and RAMDISK as shown below:
#define ROOT_DEV FLOPPY
#define RAMDISK 657
and add the following line after the definition of CFLAGS:
CFLAGS := $(CFLAGS) -DMAXTOR_7213
3) cd to the /usr/src/linux directory
type "make config" and answer the questions however you like
type "make dep; make clean; make zImage"
4) Pad the file zImage out to 512k bytes using the command:
cat zImage /dev/zero | dd bs=1024 count=512 of=zImage512k
5) Insert the original a1 disk into the drive and type:
dd bs=1024 skip=512 if=/dev/fd0 of=a1-512k
6) Insert a new formatted floppy into the drive and type:
cat zImage512k a1-512k | dd of=/dev/fd0
This is your new a1 bootdisk.
7) Now remove the ramdisk from the original kernel you built:
rdev -r zImage 0
8) Tar and zip this file:
tar cf - zImage | gzip >Image.tpz
9) Insert the a2 disk into the drive and mount it:
mount /dev/fd0 /mnt
10) Copy the new kernel onto a2:
rm /mnt/Image.tpz
cp Image.tpz /mnt
umount /dev/fd0
11) Now you should be ready to install.
Good luck,

Disclaimer: I do not have a PS/VP. I have a Gateway which I used to help
out a friend. I have not tested this a whole lot.
