I assume in first instance you meant "ms" to be microseconds and in the second instance it means milliseconds. Regardless, your timing numbers are way to high and conflict with your later estimate of a max thruput of 5 MB/s. >When using Demand Transfer mode and 16 bits wide DMA, transfer speed >maxes out at some 5 MB/s, so 64 KB would take some 13 ms. This is still ^^^^^^ >longer than the refresh period (4 or 8 ms, I believe). I always assume that a DMA /transfer takes four or five cycles (depending whether it's a zero wait state device and/or how quickly your memory controller recognizes the DMA request from the device). Therefore, on a 10MHz bus that's about 500 nsecs per transfer, not 3 usecs. And 64KB would take atleast 35 milliseconds, but since the CPU gets to use the bus inbetween each byte transfer figure 70 to 100 msecs typically. My guess is that a 10MHz bus probably maxes out at 1 to 1.5 million transfers per second and might go as high as 2 to 2.5 million transfers per second if you put the CPU to sleep. ------------------------------ From: mm@oasis.icl.co.uk (Martin Mortlock - temporary user) Subject: Query all IRQ's Date: Wed, 18 Aug 1993 09:39:46 GMT I am really impressed with the startup messages, using syslogk I can see all that wonderful info from the SCSI startup code and diagnose all sorts of problems.

For an SLS installation: Look for a directory /usr/lib/timezone or /usr/local/lib/timezone. In the directory you should find a file called "time.doc". It will tell you how to set up the timezone information. If you can't find the files/directories, look in /install/installed and check to see if you installed the timezone package.

Each of us who does know how to compile things, and will develop/port software, will take advantage of it, and (more or less) freely share the result. I can see 100,000 computer literate people packaging up Linux with their favorite software, and handing it out to 100 friends each. That is something that is illegal with MS-Windoze. This "plan" nets Linux 10 Million users! (but only 100,000 USENET subscribers :) > The one thing I do fear, however, is how Linux will adapt > to the changing architectures.

So much of the source is c, and the concepts of the assembler fraction are so sound and out in the open, that Linux will have a tremendous positive effect on freely-distributable operating systems forever. Nobody will ever be able to un-spend all the effort Linus et al. have put into this project. Now any (ambitious) cs student with a big hard disk can take the Student Project RISC of the Month and port a real OS onto it. (Based on my experience, this will be much easier after the first port, like the one apparently in progress for MIPS architecture, because that port flushes most of the machine dependencies into the open.) - Larry Doolittle doolittle@cebaf.gov ------------------------------ From: tvd@controls.ccd.harris.com (Tom Denham) Subject: Tape Drive Advice Wanted !

I think the GNU version numbering scheme system is simplest after all (after I've spent most of my life inventing all sorts of comprehensive and overly complex ones): major.minor.patch where each field is a nonnegative integer. At least I think this is the scheme they use; perhaps it's documented somewhere. So I don't understand why SLS has to be "1.03", which implies a two-digit limit to the second field, and why there have been so many version of 1.03 rather than 1.3.0, 1.3.1, and so on.
