Date: Mon, 29 Oct 2007 07:50:15 -0700 (PDT) From: John [EMAIL PROTECTED] Subject: RE: [LIB] speed gain using flash card Hello Avi Its a lot of work. Basically I matched the ram upgrade module port to a standard 144 so-dimm pinout. So I believe a standard 60ns sodimm module can be used to increase ram. So I have a old 32MB libretto module. What I am doing is first removing the chips an the board then connecting so-dimm sockets to the module using 32 gauge stranded wire. I am soldering the wire to where the chips were soldered and to the socket itself if need be. Once that is done I am going to run the socket into the hard drive bay and fix it to the side. the pinout for the libretto ram port is in the Libretto 100 maintanence manual. john --- Avi Cohen Stuart [EMAIL PROTECTED] wrote: Date: Mon, 29 Oct 2007 06:01:26 +0100 From: Avi Cohen Stuart [EMAIL PROTECTED] Subject: RE: [LIB] speed gain using flash card John, I am very interested in the technical details on the 64MB libretto upgrade.

I am getting 4 MB as opposed to 1.5 to 2 with the hard drive. I should expect 6 and 8MB with the extreme III and IV. AFAIK (based on a vague reminiscence and a google search) the theoretical maximum data transfer speed on an ISA bus is about 6 MB/s. As the Lib110's HD is attached through a 16 bit ISA connection (without DMA), that 6 MB/s is about all you'll get. Or am I wrong here? (hopefully not, for your sake) I knew there was some sort of limit, I thought it was 32 MB/s about half of the memory subsystem. But that could be the pci limit. I am also using a second flash card for a virtual memory drive but it is an old one so only gives hard drive speeds. If I updated that with a newer one I would think the increase in speed be noticalbe in swap file use. How did you connect that 2nd one? thru the PCMCIA slot? Yes. I remember I found an external -PCMCIA, or rather, Cardbus- HD to be clearly faster than the internal one (I had a 7200 rpm Hitachi inside). There was also a thread on this in the mailing list. the differance is in the clock speeds, ISA is slower than PCI. I notice a real reduction in temperature also using a solid state drive. My libretto was always having to slow down to cool off but it is very cool now when it runs. Anyway it all sounds like a bright idea to me. Thanks. I like it so much because the libretto is perfectly silent when it runs now too!! Any idea about battery power savings using flash rather than rotating storage? I don't think there is much differance, my libby reports about 5 1/2 hours usually but I notice I don't have to plug in the adapter now until I am ready to shut down. It kinda did that before but not so routinely. Battery life is so dependant on what a person is doing. Where I really notice a differance is in spin up times. There are none, with a hard drive spin up times were very noticeable. Sometimes I feel a bit sorry to have decommissioned my L110; it merely serves as a sort of book stand, right on top of a What do you use in place of it? I tried the U100 but it fried like twice on me. It was a piece of junk. They run too hot and Toshiba doesn't cover them under warrenty. My 110 keeps plugging along no matter what:). much older DEC 450SLC/e notebook (with a 50 Mhz 486-DX2 inside - wow). Sometimes I start them up just for fun, like today when the clocks in my place must be reset to winter time. BTW have you ever had any luck upgrading the RAM beyond 64 MB? (I remember you were busy with that). There were some guys who have fitted And still am:). I am fitting a wire buss to an old libretto 32MB ram upgrade board. I am going to solder the buss to a couple, maybe three, of so-dimm sockets. I am going to run the so-dimm sockets into the hard drive bay, where I have room now (I was just waiting until compact flash capacity got

Date: Mon, 29 Oct 2007 08:08:13 -0700 (PDT) From: John [EMAIL PROTECTED] Subject: Re: [LIB] speed gain using flash card The main problem a solid state drive helps is the heat issue when using a hard drive besides speed. I would think it would work great on a 70 and since you install in the IDE port you only need drivers if you wanted to use the secondary drive as virtual memory. One thing, virtual memory is supposed to be run from a secondary disk anyway utherwise it doesn't really work well. The Sandisk Extreme IV is supposed to have write speeds of 40MB/s so even if we get only half that it is close to 1/3 of the RAM system which is 60MB/s that is pretty fast. john --- [EMAIL PROTECTED] wrote: Date: Mon, 29 Oct 2007 06:32:18 EDT From: [EMAIL PROTECTED] Subject: Re: [LIB] speed gain using flash card I was wondering how any of this applied to earlier Librettos.
