If my memory serves correctly, SCSI started off as SASI - developed by Shugart Associates for some marketing reason or other. It met a need and was clean enough that other vendors started supporting it. Eventually, ANSI standardised it. It was never designed to be a future-proof storage interface that would underpin the world's low to mid-range server market. In the beginning there were 6-byte commands. These were limited to 21-bit block numbers but since no-one would ever have devices with more than 2^21 blocks (typically 1GB) there was no need to allow for a larger block number - which would make the command larger and slower to transfer to the target. Of course the first people to experiment with large (1GB) disks discovered a fairly serious disadvantage of 6-byte commands when the top bit of the block number got lopped off and the outside tracks of the disk (boot-block, primary or only superblock etc) got over-written by data intended for the inside tracks. 10-byte commands were therefore introduced. These extended the block number to 32 bits and allowed a larger transfer size as well. And the limits of 32-bit block numbers are now being reached and longer commands have been defined to allow for bigger storage devices. 6-byte commands still have an advantage for transfers that fit within their limits (block number and transfer size) - they are smaller and therefore faster to transfer. SCSI commands (and command responses) must be transferred asynchronously and USB 1.x is fairly slow so the less data to transfer the better.

For anybody who's looking to build cheap but reasonably powerful servers or desktop machines, this looks like a winner. seconded - i'm hugely chuffed with mine, it runs really quiet. I haven't run any real benchmarks, but in terms of feel it might be equivalent to maybe a 500-600MHz PIII. The total server parts list ran about $350 with shipping, including 7200rpm IDE drive and a 2nd 100BT card (Linksys LNE100TX.) I haven't tried X or the sound capabilities so I'm not sure how suitable it would be for a desktop; I also haven't tested whether the IEEE-1394 would work under FreeBSD. For a low-end server, though, it's pretty nice, and moderately quiet too. XFree86 is ok under x11-servers/XFree86-4-Server-snap's via code. general desktop performance is fine. sound works too, y'normal pcm(4). i've had no joy using the integrated castlerock mpeg2 decoder in the graphics chipset, and indeed mplayer threw a hissy fit with it. given the youth of the X stuff, this is likely to get better. The motherboard includes integrated CPU, 1 DDR slot, 4 USB, 2 serial, 1 parallel I/O, 2 IEEE-1394, floppy port, dual IDE, SVGA out + SVHS TV out, 10/100 LAN, and 1 PCI. The IDE interface works at ATA133 under FreeBSD 4.8; the VIA/Realtek ethernet is recognized as vr0. The CPU integrated on the motherboard is a 1GHz VIA C3, an IDT descendant - the newer Nehemiah core which is claimed to have better instructions per clock than the older VIA cores. Matt Dillon posted about the earlier EPIA boards a while back, so I thought I'd add a note that this one also works well. -- Clifton, not a VIA salesrep me neither!

installation panic
Hi, Thank you for reading this email. I have been trying to install FBSD on my advent laptop 7018 (see specification below) It came package with XP home. Well I used Partition Magic 8 to create a partition before C drive. Well I created it as primary unformatted. So FBSD boot can use the space before the 1,024 cylinder. When I set the unformatted partition active ready for install then I boot from my FBSD CD well there seem to be a kernel panic. It keeps on going in circle rebooting several times. Please tell em if there is a possibility of installing FBSD on this hardware or I am trying to do the impossible. Maybe I need to install FBSD clean on the whole drive. Then create the slice an reinstall XP. But I'd rather not do that ,too many data to back up. try with moving and creating the partition first with PM8. FIPS won't work on XP anyway so i'm stuck @ the moment. This section read only if you want to : Now I am keeping the microsuck OS because I need it for my course work and also until i get all the hardware to function under FBSD example WI-FI Lan. I like challenge and experimental learning and I think FBSD OS has a lot to go for. I like to get down to technical. Maybe in the future I will have to do some system administration in my line of duty I was going for Linux [RedHat 9.0]. However FBSD can emulate linux and run ported applications. I'm a newbie to Unix and I hate microsuck. But have a long time macintosh experience user. Well the latest OS X Darwin has its origin from FBSD. OS X is unix based. Well when I start looking under the hood of OSX well my unix interest has grown a lot. I decided that I should run FBSD on my wintel machine because I was getting tired of microsuck.

Request For Help: KSE for sparc64 and alpha
All, Time is winding down for the 5.2 development cycle, and one thing that we are missing is KSE support on sparc64 and alpha. We would dearly like to have KSE supported on all platforms for the release, so we are asking for help. Sparc64 is missing some userland pieces, and alpha is missing some kernel pieces. Anyone interested in helping should contact Dan Eischen [EMAIL PROTECTED] and David Xu [EMAIL PROTECTED] for more information (and also contact Jake Burkholder [EMAIL PROTECTED] for sparc64). Thanks!
