General Questions

-

-No multicast or IPv6 - "le0: not multicast capable" (top) -

-

The LANCE revision C chips used in - some sun3s (not the sun3x) have a bug which sometimes results in garbage - inserted where the first bits should be, with the correct bits shifted later. So - instead of the destination MAC address at the beginning, you get something - random looking.

-

The workaround is to examine the beginning of the packet and throw away - anything that's not for us (my MAC or broadcast). Unfortunately this prevents - the use of multicast.

-

The LANCE Rev. C chip was probably only used in the 3/50, so on other sun3 - machines you should be able to build a - kernel without the line:

- 
options LANCE_REVC_BUG
- -

-Running diskless 3/80 with ESP driver - "esp: SCSI bus reset." (top) -

-

- This message is a symptom of a bug in the - esp driver on diskless systems. The ESP (Emulex SCSI Processor) driver in - NetBSD/sun3x has a bug that causes it to enter an endless loop when it probes an - empty SCSI bus. To work around this problem, use a kernel which does not have - the esp device driver, or plug in at least one powered SCSI device into the bus.

- -

-SunOS 4.1 Compatibility (top) -

-

NetBSD/Sun3 features extensive binary compatibility with SunOS 4.1.x - programs. Static SunOS executables will run without any extra setup.

-

To run dynamic executables, you'll need to provide the dynamic libraries that - came with your SunOS installation. SunOS programs that will - not work include those that use the SunOS kvm library, - certain (low-level) disk manipulation utilities, and programs making explicit - use of Sun's STREAMS subsystem. Check the compat_sunos(8) manual page - for more details.

- -

-Booting SCSI devices at different targets (top) -

-

All sun3 and sun3x monitors support booting from SCSI devices. Most users - will be familiar with booting from the monitor device sd(0,0,0), - which they know means booting the SCSI disk at target zero. However, determining - the monitor device name for booting an arbitrary SCSI device can be confusing.

-

A monitor boot device takes the form - dev(cntrl,unit,part). - dev is two letters, and cntrl, - unit, and part are hexadecimal - numbers.

-

For SCSI disks and CD-ROMs, dev is sd. For - SCSI tapes, dev is st.

-

For all SCSI devices, cntrl is the number of the SCSI - controller the device is attached to. For a machine with a single SCSI - controller, cntrl is 0.

-

For all SCSI devices, unit identifies the SCSI target - and logical unit number of the device. Exactly how the SCSI target and logical - unit number are combined into the single number unit - depends on your machine type and ROM revision, and whether or not the device is - a disk, CD-ROM, or tape. Use the tables below to figure out how - unit works on your machine.

-

For SCSI disks and CD-ROMs, part selects the partition - to boot on that disk or CD-ROM. The first partition is 0, the - second partition is 1, etc. Normally, part is - 0, since the first partition on a disk is usually the bootable - one. Common exceptions are booting a miniroot that has been written to the swap - partition, in which case part is 1, or booting - a CD-ROM that contains different bootable partitions for different - architectures, in which case you have to know which partition boots your - architecture.

-

For SCSI tapes, part selects the tape segment (also - called "tape file") to boot. The first tape segment is 0, the - second tape segment is 1, etc. You will need to know which tape - segment is bootable for your architecture in order to give the right - part.

-

Finally, these are the tables that demonstrate how unit - works on various machines. They list sd monitor devices for disks - and CD-ROMs, and st monitor devices for tapes, all at different - SCSI targets. These tables assume that you want the first SCSI controller - 0, and the first partition or first tape segment - 0. Also, because many Sun 3 models use the same CPU board, to keep - these tables simple Sun's CPU board code names are used wherever possible.

-

The above tables also assume that you want SCSI logical unit number zero. The - SCSI specification allows one SCSI target to contain different logical units - (also called LUNs). Virtually no SCSI devices make use of this feature, and have - only a single LUN, zero. However, if you know you have a disk at a LUN other - than zero (early Sun SCSI disk setups do), you can add the LUN number to the - unit value, noting that unit is a - hexadecimal number.

-History of NetBSD/sun3x (top) -

-

The sun3x port of NetBSD was initiated by two independent groups of - developers. The first group, headed by Gordon Ross and Jeremy Cooper, began work - in March of 1996 with the (then) current sun3 port and the intent to create a - new pmap system that was not based on the hp300 m68k code. Their work is the - officially supported version of NetBSD/sun3x.

-

The second group, headed by Tsubai Masanari, also began with the sun3 - distribution but instead choose to use the traditional hp300 m68k pmap. This - approach allowed them to get a fully running system in a matter of weeks. They - were the first to successfully integrate the SPARC Enhanced SCSI Processor - driver into the kernel, proving that the Sun3x was indeed half SPARC, half Sun3.

-

Although the currently supported NetBSD/sun3x is based on Gordon and Jeremy's - work, they are indebted to the second group for their innovation.

-

Between NetBSD 1.3 and 1.4 NetBSD/sun3x was merged into NetBSD/sun3. They - build separate kernels, but share the same userland, and kernel build tree. -
