hi again, first of all i'd like to thank Panu Matilainen for his reply to my question, and in fact the problem was with the cd reader, as it doesn't read cd-rw right, thanks again. Now for a problem i have, when i run buildinstall /mycd, i have the following error msg: Building images... (... snip ...) mke2fs 1.23, 15-Aug-2001 for EXT2 FS 0.5b, 95/08/09 Wrote /tmp/makebootdisk.tree.3962 (612k compressed, 1079k free) Wrote /mycd/images/boot.img (9k free) sed: couldn't write 19 items to {standard output}: No space left on device sed: Couldn't close {standard output} /mycd/buildinstall.tree.32043/mk-images: Failed to copy messages from /mycd/instimage/usr/lib/anaconda-runtime/boot/ to /tmp/makebootdisk.tree.3962. and it exists like this. i tried to find wich .img it was trying to build, but had no success. Anaconda is changed, it has the XFS patch in it, the dist has only the new updates, plus a new kernel (2.4.17, BOOT-2.4.17, doc-2.4.17, source-2.4.17). as i don't need the pcmcia for nothing i left the kernel-pcmcia as the original kernel-pcmcia-cs-3.1.27-10. oh, and sgi guys increased the ramdisk size in syslinux.cfg to 8192. The question is, anyone knows what seemd to be the problem!?, if it can be solved, and if it will boot correctly (ad i think it's a boot image size problem :/ ) thanks for all the help. Rui Barreiros
