Hi, My friend Storm Lee encountered some install related problem in moving to fedora core 4. Would anyone please help him out? Here is some of the log in different consoles, I just forward his letter here. Thanks! ============= during hardware testing, report ide error "cache flushes not supported" dma error .no response wait a moment, fedora installer start when choose the install source , I put the iso on d:\fc4 ,so I chose hda5. the out of character interface is : mntloop loop7 on /tmp/loopimage as /tmp/hdimage/fc4/FC4-i386-disc1.iso fd is 1 2 mntloop loop0 on /tmp/runtime as /tmp/loopimage//Fedora/base/hdstg2.img fd is 12 failed to mount loop0:invalid argument umount loopback /tmp/runtime loop0 Here, i think, hdstg2.img can't be found .but disc1.iso is already mounted why hdstg2.img ? in the other character interface ,out is unable to load NLS charset utf8 iso9660 Extentions :RRIP_1991A unable to identify CD-ROM format VFS:Can't find an ext2 filesystem on dev loop0 cramfs: wrong magic fat:invalid media value(0x19) VFS:Can't find a valid fat filesystem on dev loop0 that's all.I hope you can find where the problem is .:) i use the grub for dos , tomorrow i can try to boot my machine from the boot.i so -- bbbush ^_^
