I mark the line i wish you pay attention to.i have two questions: one is why the hdc lost the interrupt. the other is why the bootp time out. i test the host dhcp configuration with win98 as client. The dip switch on cpu board is set to : sw2 01111,sw3 11011 (1 means ON) BTW,who could tell me every bit of the two dip switch mean? I couldn't find document about it. The dip switch on main board is set to: sw1 11111010 ,sw2 11111111. The type of main board is "ppceval-sp3 rev x3". the CPU board is "m98ppmc8240 rev x2" .linux kernel is Mvista Hard Hat Linux 2.0 for ppc 82xx. My hard disk type is "Quantum fireball 3.5series 30.0GB". the following is bootup message: DINK32_KAHLUA >>dl -k #>ascii-xfr -svn -l 10 vmlinuz-motolola-sandpoint.srec>/dev/ttyS0 DINK32_KAHLUA >>go 900000 loaded at: 00900000 009091B8 relocated to: 00800000 008091B8 zimage at: 00906000 00998F41 avail ram: 00400000 00800000 Linux/PPC load: Uncompressing Linux...done.
