I've been playing around with pc card flash memory and have been disappointed with the data xfer rates. I would like to try out the ADP-CF2-PC32 PC CardBus Type II to CompactFlash Type II (HS-CF32A) adapter offered by synchrotech which supports 32 bit access and dma. My laptop computer has the hardware support (ti 1410 controller).

See < http://www.synchrotech.com/product....01.html >
for details about the adapter. It's interesting that there is a special mac os 10x driver for the card.

Before I run out and buy this adapter or any other 32 bit access adapter for flash memory, I would like to know if the card manager supports this card.

Does anyone have any experience with type of setup?

Thanks

I have no knowledge about that particular card/setup.

However, I can say that on older laptops, such as mine, in order to even attemtp to use card bus pcmcia cards I need to use the boot option pci=assign-busses

HTH

Thanks for the pci=assign trick, as it turns out that fixed a different problem I was having.

I've put aside the compact flash cardbus initiative for awhile and instead have focused on getting a usb2 cardbus adapter to work first. I'm happy to say I have this working and now have much faster web server performance. The system now boots from floppy disk then continues the boot from an integrated usb1 port memory stick. I have the opt directory web server located on the cardbus usb2 memory stick.

What I would like to do next is have the system access the cardbus usb2 memory for all the applications. I suppose this means putting the knoppix image in usb2 memory and configuring the system to go to the usb2 memory to fetch applications.

So how do I go about dong this? Any ideas will be greatly appreciated.

Thanks

You can use the mydsl= cheatcode option. See the wiki entry on cheatcodes for more info.

Thanks for the reply. I had already looked at the cheatcodes but it's not clear to me how to exactly go about this. I presume this is the cheatcode that should work?

[root={hda1 / sda1/ floppy } In frugal installs, specifies the partition where linux cloop file KNOPPIX resides.]

Do I then simply copy from the boot usb flash drive /knoppix to where ever the root cheatcode points to?
Thanks

Update:
I tried using the root=sdc1 code which points to my cardbus usb2 flash drive which has a usb zip system install on it. This did not change anything. Applications still go my sdb2 usb boot flash drive to get the programs.

Wrong code... it's mydsl.

Unless you meant something else other than mydsl extensions for your "applications"?

Posted by Big_Pc_Man on Sep. 08 2007,12:41

Yes indeed, I see what you mean.
Ok, I tried setting mydsl=sdc1 (cardbus usb2 port) and again there was no change. Firefox for instance was still loaded from the sdb1 usb port.

Any other ideas?

Did you put the files in the correct location? Should be in .../mydsl

Posted by Big_Pc_Man on Sep. 08 2007,18:16

Let me get this straight, I'm suppose to put the entire /knoppix image in the /mydsl diectory?

Posted by ^thehatsrule^ on Sep. 08 2007,20:12

No, that is not a mydsl extension. That's the base DSL image.

What exactly are you trying to achieve?

I thought we had some confusion here. At a high level I'm trying to boot up from a slow floppy disk and usb flash drive and then run the entire system out of a separate fast (usb2) flash drive. I can't boot directly from the usb2 flash drive because it is attached to a cardbus usb2 adapter card which of course requires card manager for activation. Getting card manager to run from a single floppy boot system is the subject of another thread I have active. This looks possible but not easy to accomplish.

What's the contents of your floppy disk, your slow flash drive, and your fast one?

Posted by Big_Pc_Man on Sep. 09 2007,20:10

floppy=bootfloppy-usb image; slow usb=system as created by dsl usb-zip create flash pen drive tool (sdb1&2); fast usb=duplicate of sdb1&2 (sdc1&2).
