Sounds good.  Any issue with making SWAP like 4GB?  Does that slow the system vs. 2GB?  This is a 320GB drive, after all...


Depends on whether or not the VM subsystem supports physical address extension. I really don't know if it does or not. I initially thought about using a 20GB swap partition for OS4.1, but in the end went for 2GB.

i guess you can connect a 1.44 floppy via USB ?


I tried this once and it didn´t work. ... Wait ... let´s try again:

connecting drive - done (it´s an IBM  USB Portable Diskette Drive)
pulling out an old dos disk that is known to be working - done (720k DD)
inserting - done (drive spins and blinks led)
look on desktop - no icon for the drive

USB drives usually present an Icon if they are FAT-formatted, so I guess it isn´t working.

Hmm, the Radeon 9250 I ordered for this SAM440ep-Flex uses 64-bit memory.  It seems most 9250's used 128-but memory.  Anyone know if this makes a huge diff in practice?

Hm....

I'm truly excited for you Blakespot!

I wish it was me putting this system together...

Best of luck with it!

yeah the 64bit vs 128bit memory interface makes a huge difference, especially at high resolutions. its WELL worth finding one with a 128bit interface.

As of April, SAMimgas did not recognize over 128MB of video RAM on the card.  Is that still the case?  Even still, I suppose the 128 of a 128-bit board's 256MB of video RAM would be accessed via the same 128-bit channels, so...

128 max at the time IIRC. Maybe 256 in the future.

I have 64-bit version myself and running 1920x1080 where can I experience slowdowns?

Got it together.

This Radeon 9250 128MB is not listing a 1600x1200 screenmode.  What's up?

I should be able to do 1600x1200 on this screen...?  (1280x1024 is max listed in ScreenModes...)
