Re: 7.1 on a IBM 43P, 7248-132
Finally have a working firmware for the SCSI2SD device (replaces the
SCSI2 HDD). This firmware works with the 7248-132, but in general
probably supports anything using a Symbios Logic 53c810 (fast scsi)
If you've been able to load NetBSD on your machine, have you had any
trouble with the integrated ethernet freezing the machine when trying to
bring up the interface?
"ifconfig pcn0 up" will cause my machine to lock up.

No problem, attached are the two config files. If they don't show up,
I can paste them into emails.
Some quick pointers on some differences from the generic config:
-WD is disabled. I originally tried to use IDE drives since the SCSI
drives I have are somewhat loud. Could not get the system to boot off
of them, so decided not to use them. You might be able to use IDE for
-Stripped out PCMCIA.
-Removed any options for PCI/ISA that are not specific to this system.
-There are options turned on for a PCI NIC and an ISA NIC.
-USB subsystem enabled.
-The boot device is specified as SD0 and using FFS. This was due to
the boot process not automatically finding the root drive (still
unsure of the root cause). This will allow the boot process to reach
the login prompt without prompting for the root device.
On a side note, I'm working with the developer of a SCSI2 to SD card
adapter to get it to work with the 7248. He frequently provides
updates for the firmware so this may become an option if you want
quieter solid state storage.

Finally got this to work:
I had to recompile the kernel to add in support for a PCI NIC and PCI
USB card and took the opportunity to trim out some things that were not
needed or planned on being used (WD).
I was wrong about the 2MB limit but ended up making a small kernel to
put into the PReP partion based on the INSTALL_SMALL kernel config.
I can post the kernel config files if you would find it useful.

Using sysinst_small.fs in the PReP partition allowed loading of the
boot loader. The boot process will proceed to a point where it
requires user input to specify a boot device because it does not find
one by default. Providing it "sd0" will allow for the generic kernel
to load (when going multi-user?) and provide the login prompt.
If I enter "boot -s" at the boot loader prompt (single user), it will
boot into sysinst.
sysinst.fs will boot when I network boot with BOOTP/TFTP. I have not
tried writing that into the PReP partition (as I did with the small
version) but I suspect it would work because it is less than 2MB in
sysinst_com0.fs used in the same way mentioned above will not work for
me. I have not tried sysinst_small_com0.fs in this manner.

Interesting. At a first glance the log says that the scsi driver is

Found that the kernel size is the issue by using mkbootimage with
install_small.fs and dding that into the PreP partition and
boot. Will end up doing the small kernel work around mentioned
referenced email thread.

One other thing I've noticed with this machine is interactions

going to install the NetBSD binary packages from a NFS mount, but
system would lockup halfway through the installation of the
package. I bypassed this issue by using the CDROM instead.
