If it finds the CF card but won't boot from it, it may just be a boot loader problem (fdisk /mbr might help this). If it can't find the device at all, then you may have to fiddle with the BIOS settings. If it's recognized in the BIOS and you can set it as the boot drive, then you should be good to go - the Linux install will set up the boot loader for you. > All help and >advice gratefully received.

The 133x card is therefore about 20 MB/second, which is pretty slow by hard disk standards. It should be OK to set UDMA on, since the BIOS or Linux will fall back to the highest supported mode anyway. I think LBA is the best mode in general, but you may need "Large" for one reason or another. - Steve ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
