I will work 'mbxroot.full.tgz' file at 'ftp://linuxppc.cs.nmt.edu/pub/linuxppc/embedded'. I plan to boot from NFS after compile at PowerPC 603 machine. I have some question following: (1) Can I boot from floppy of the MBX system? if, yes. what is the method? (2) I would like to know configuration for network booting, and after network booting, can I install linux to the HDD of MBX system? if, yes. what is the method? (3) Can I use the MBX system for self-hosted development system? (4) I compiled linux 2.2.6 for MBX system at PowerPC 603, then I tried to network booting, but didn't booting. what is the problem. following is the console display message. ================================================================== EPPC-Bug>pl 20 0 Network Booting from: MPC860, Controller 20, Device 0 Loading: /sys/mbxroot/zImage Client IP Address = 210.96.178.73 Server IP Address = 210.96.178.72 Gateway IP Address = 0.0.0.0 Subnet IP Address Mask = 255.255.255.0 Boot File Name = /sys/mbxroot/zImage Argument File Name = Bytes Received =&512723, Bytes Loaded =&512723 Bytes/Second =&256361, Elapsed Time =2 Second(s) loaded at: 00210000 0030E42C relocated to: 00100000 001FE42C board data at: 003F4558 003F4580 relocated to: 00200100 00200128 zimage at: 00216000 0027BCB3 avail ram: 0030E42C 00400000 Linux/PPC load: root=/dev/nfs nfsaddrs=210.96.178.73:210.96.178.72 nfsroot=210.9 6.178.72:/sys/mbxroot Uncompressing Linux...done.
