Hi all: I have recently purchased a HDD and CDRW for my machine to improve the usability somewhat. However, on installing the devices, in any combination of jumpers and configurations, I seem to be getting interupt errors. The OS boots as far as "Scanning for new hardware" and hangs. When I do ctrl+alt+F10 I see the following messages: bad special flag 0x03 lost interupt no flushcache support This is repeated endlessly and it never boots. The device is dual boot with RedHat and that gets past this and shows the devices in the hardware list but they don't work. Also, the boot up shows that there is a floppy but I can't get that to work as it also has disk i/o error messages. Is it pilot error or a bad motherboard? Any help much appreciated. Paul PS Hope to see you all in Danbury
