Here is one I found. It's a 16bit ISA card, with four ports. Well built, good materials, and high-quality as far as I can tell. Connection is through a 37 pin D-shell connector on the back of the card, they supply an octopus with 20 cm arms and good quality male 25 pin connectors in the other end with the card. There are four sockets, and they can take all the usual chips, including a "16650" chip with 32 bytes fifo's and crtscts and xonxoff in HW. We see that chip as 16550A and run happily on it, though we don't support the advances features (yet :-) Each port has a jumper-bank to select A9-A3 and "enable", and the irq's can be steered to irq 2,3,4,5,7,10,11,12,14 or 15 for each channel. Irqs can be shared, separate, or some mix. Waitstates can be set to <= 8Mhz <= 12Mhz <= 25Mhz > 33Mhz It works out of the box with this spec: device sio4 at isa? port "0x2a0" tty flags 0x705 device sio5 at isa? port "0x2a8" tty flags 0x705 device sio6 at isa? port "0x2b0" tty flags 0x705 device sio7 at isa? port "0x2b8" tty flags 0x705 irq 5 vector siointr As far as I can tell, they also have a version with twice the above on one card, ie. 2 times four ports.

FreeBSD supports a wide variety of hardware. This is great for those who want to install FreeBSD on thier existing systems, but it's overwhelming for those who are shopping for new hardware specifically for a FreeBSD system. I'd like to compile a list of the top 1-4 recommendations for each category of hardware. This way, buyers can look into a handful of possibilities rather than the long list of supported hardware. If you are an avid FreeBSD user and have installed, used, and/or tested various hardware products, please e-mail me your submissions with comments to terryl@cs.stanford.edu. I will compile a list and post the results. I will also submit the results for inclusion in the FreeBSD Web site. I suggest the following criteria for evaluation and comments: Compatibility - should be rock solid with the least amount of installation issues e.g. 3c509 card is out Performance - please provide any specs you have or tests you may have performed, are performance features supported Price - please provide a street price and source Reliability - does it break down, is there good service and waranty Features - any special features or functionality Current submissions (just the beginning of course): Motherboards/CPUs: ASUS motherboards (which ones?): PCI/I-486SP3G - 486 motherboard w/ on board NCR 53C810 PCI SCSI Controller Street Price? Pentium Boards? ISA Ethernet: SMC Elite Ultra $95 (the clear choice?) PCI Ethernet: SMC, Compex or DEC DC21040 based ethernet Specific models? Prices? Details PCI Video: #9 GXE 64Pro PCI SCSI controllers: Adaptec 2940 More categories: ISA Video ISA SCSI controllers CD-ROMS Sound Cards I/O Cards SCSI Hard Drives IDE Hard Drives Mouse Hardware what else?

It all depends on what you're doing with it. In my machine at work I have a 400 meg drive dedicated to swap. The circuit synthesis and simulations we run here need LOTS of memory and swap. The "big" machines in our group have 256M of memory and a 1 Gig swap drive. I suppose splitting the large swap-space over 4 disks is probably much more efficient than having just a single big (and, might I add, LOUD) disk, but then who wants to be efficient? ;) brian From owner-freebsd-hardware Wed Aug 23 11:12:04 1995 Return-Path: hardware-owner Received: (from majordom@localhost) by freefall.FreeBSD.org (8.6.11/8.6.6) id LAA15929 for hardware-outgoing; Wed, 23 Aug 1995 11:12:04 -0700 Received: from penzance.econ.yale.edu (penzance.econ.yale.edu [130.132.32.100]) by freefall.FreeBSD.org (8.6.11/8.6.6) with SMTP id LAA15923 for ; Wed, 23 Aug 1995 11:12:02 -0700 Date: Wed, 23 Aug 1995 14:15:05 -0400 (EDT) From: -Vince- To: "Rodney W.

The results so far are not encouraging: My test setup is: +--------------+ +----------------+ | P90 PCI | | 486DX4/100 PCI | +--------------+ +----------------+ | | crossover cable (100baseTX) | main ethernet (10base2) | ----------------------------------------- ------------------------+------- Both machines are running 2.0.5R(*). The main ethernet and the two-station network are addressed as two separate class C networks. The second interface in the Pentium box is an SMC Etherpower 10. The Pentium box is a made-by-intel Triton-based motherboard. I have tried two different 486 machines, one made-by-intel motherboard and SCSI discs, one Taiwanese (Gigabyte?) motherboard with IDE disc, with the same results. My basic test is FTP-ing a large file (eg. kernel.GENERIC) between the two systems. Problems: 1) When operating at 100Mb/sec, there seems to be substantial (random) packet loss going from the Pentium to the 486. When you fluke an error-free transfer throughput of about 2Mbyte/sec is achieved, but more commonly there are pauses of a second or so giving a net througput of only 300kbyte/sec typically. If configured for 10Mb/sec (ifconfig de0 -link2), a consistent throughput of 1Mbyte/sec is observed, with no pauses. Similar pauses are also noticable using telnet, and also if the 486 is re-booted to Windows, accessing a Samba server on the Pentium box. 2) Regardless of the interface speed, an FTP transfer from the 486 to the Pentium runs smoothly (fast) if the FTP connection was made to the address of the 10/100 interface in the Pentium box, but if the address specified was that of the other interface in the same machine, throughput starts slow but gradually speeds up, reaching full speed after about 25Kbyte. In an attempt to eliminate the one piece of hardware I could replace, I changed the SMC-supplied cat5 UTP cable (with RJ45 connectors) by a homemade cable using IBM type1 cable and DB9 connectors, using the other connector on the cards. My homemade cable appeared to work a bit better for problem 1, but by no means eliminated it (so the difference may be experimental error). Since others have reported good things with these cards, I must be doing somthing wrong. Do I have a hardware fault, FreeBSD driver problem, or is 100Mb/sec just too fast for 486DX4/100 boxes? Any ideas appreciated..... Andrew. ----- (*) initially tested with pure 2.0.5R. I subsequently checked the driver in -current, which had changed very slightly, so built a 2.0.5R kernel with the de driver out of -current. No change.

Most times when you start to _use_ more than 2x physical memory for swap you are taking large performance hits. This may be acceptable depending on what it is you are doing. Since I happen to catch you are playing with what appears to be logic synthisis stuff, the performance hit is the only way you will ever run this type of stuff. I have done a far amount of work in supporting Intel in the area of clusters of HP9000/7XX (they upgrade these things to the fastest boxes avaliable every 6 months, thus the XX) for the purpose of running Synopsis (large commercial logic synthesis software). Typical machine is 512 to 768MB of physical ram, and 1 to 2G of swap. >From watching the systems with ``Glance'' (an HP performance montioring tool) we learned that once swap usage hits about 4x physical memory the synopsis jobs slow to a crawl and it is best to partition the synthesis run and restart it rather than let it grind away forever. Note, this is one specific example of large memory large swap configurations, it works fairly well for the intended purpose. I would never want to log into one of these systems and try to do interactive work (well, unless there was no jobs running, then there the quite NICE to use). My general rule of thumb is if the box has an interactive work load on it (ie, users running a shell) that anytime you hit 2x physical memory in swap space your paying for it badly and rather than throwing some more swap space at it you should really consider a memory upgrade. If the machine is a non-interactive cruncher (I don't consider ftp an interactive application, so this applies to wcarchive.cdrom.com) 4x to 6x is pretty much an upper limit before performance takes such a hit it becomes useless. > I don't know.

But I know that the Sparc 10 in the office upstairs was > swapping like mad when I ran stuff on it (I could almost hear the > drive down here ;). I have seen the engineers out at Intel consume as much as 1.5G of swap, but most of the time they are working with a partition of the design and use about 1G of swap. They cry wolf very loudly when a 18 hour synthesis run barfs on an out of memory error, so a close eye is keep on the upper bounds of swap useage and anytime jobs start getting close to it they are asked to watch out, and if they can repartition the design, or give us a day to chuck another 1G swap disk on a machine and target there jobs to it. > Hmm...long post.
