Has a certain amount of trouble getting detected --- keeps showing up as Anonymous Memory --- but once it's running, it works fine. Unfortunately, it's even slower than your benchmarks... Timing buffered disk reads: 64 MB in 152.29 seconds =430.34 kB/sec Timing buffered disk reads: 64 MB in 199.30 seconds =328.83 kB/sec Timing buffer-cache reads: 128 MB in 4.46 seconds = 28.70 MB/sec Timing buffer-cache reads: 128 MB in 4.15 seconds = 30.84 MB/sec It's slower than 10Mb ethernet! I should have stuck to NFS! It's reported as a TOSHIBA MK5002MPL. Any suggestions on how to speed it up? I tried turning on multcount, but that didn't have any effect, as you found out. [...] > There are several 10/100 cards listed on the compatibility page at > handhelds.org. How does one tell if a card is "non-CardBus"? That's the problem. I tried a 100Mb card we had here, and the iPAQ didn't even notice I'd inserted it. The card was CardBus only. I'd rather not order one and find out later that it didn't work. - -- David Given [email protected] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8bUVff9E0noFvlzgRAj+DAJ9pkMYn/77UjbWiFfbXKWfQckosRwCgiwGV tXcGv4mRQ04rKxfakeKMiFQ= =vZQv -----END PGP SIGNATURE-----
