Greetings, I'm trying to upgrade from Fedora 6 to Fedora 8 on an Acer Veriton 5900Pro, with no success at all. So far I've tried irqpoll noirqdebug ide=nodma cdnodma edd=skipmbr pci=nomsi,nommconf libdata.dma=1 libdata.dma=0 noapic nolapic noacpi scsi_scan=sync hwprobe=modules.pata hwprobe=-modules.pata acpi=off pci=noacpi pnpacpi=off clocksource=acpi_pm nohz=off highres=off which I've gleaned from various google searches. As far as I can see, any noapic makes it hang running /sbin/loader. As far as I can see, irqpoll noirqdebug are vital, and nolapic is lethal, otherwise the install hangs loading ata_piix driver. With all other combinations I've tried (about 30 so far) I get: The Fedora disc was not found in any of your CDROM drives. Please insert the Fedora disc and press OK to retry. Debian, and Fedora 6, install fine on the same hardware, using just irqpoll noirqdebug Are there other kernel options I should be trying ? Any other ideas ?
