hi all, Now, I can boot my SGI-O2(R5000,IP32)box by downloading "vmlinux" kernel through filebootp/dhcp, It displayed some messages of booting,but stopped at init base system by NFS,because I haven't put any base system files in the NFS root directory. I googled through all the websites I can,but got nothing I need. Where can I get the proper base system for NFS boot? Thanks for any help in advance :-P Zhang Fei zhangfei@cnic.ac.cn 2003-05-13 ============================================ R&D Division Computer Network Information Center Chinese Acdamy of Science Beijing , China Tel:010-62536760 Fax:010-62560928 Zip code:100080
