This is a 7248-133 43p. I had a lot of trouble with the early 2.6 kernels on this prep machine however 2.6.14.7 runs well (the vga console driver even works now). There is one thing I noticed different from 2.4.32 involving PCI resources. On 2.6.14.7 I get... Total memory = 192MB; using 512kB for hash table (at c0300000) Linux version 2.6.14.7 (root@oldbb) (gcc version 4.0.3 20051201 (prerelease) (Debian 4.0.2-5)) #4 Fri Feb 10 13:27:45 CST 2006 PReP architecture IBM planar ID: f7 ... PCI: Probing PCI hardware Setting PCI interrupts for a "IBM 7248, PowerSeries 830/850 (Carolina)" PCI: Cannot allocate resource region 0 of device 0000:00:0c.0 PCI: Cannot allocate resource region 1 of device 0000:00:0c.0 PCI: Cannot allocate resource region 0 of device 0000:00:10.0 The regions correspond to: Region 0: I/O ports at 80001020 [size=32] of the builtin pcnet32 ethernet. Region 1: Memory at c0800100 (32-bit, non-prefetchable) [size=32] pcnet32.. Region 0: I/O ports at 80001400 [size=256] of the Symbios Logic 53c810 scsi. Both the ethernet and scsi work fine though.. 2.4.32 remaps these... Linux version 2.4.32 (root@oldbb) (gcc version 2.95.4 20011002 (Debian prerelease)) #2 Tue Feb 7 12:30:21 CST 2006 PReP architecture IBM planar ID: 000000f7 ... PCI: Cannot allocate resource region 0 of device 00:0c.0 PCI: Cannot allocate resource region 0 of device 00:10.0 PCI: moved device 00:0c.0 resource 0 (101) to 1020 PCI: moved device 00:0c.0 resource 1 (200) to 0 PCI: moved device 00:10.0 resource 0 (101) to 1400 Is this important?? 2.6.15 BTW doesn't work at all. I need to hook up a serial console to see if I can figure out what is going on... Bob
