Hi, I recently took delivery of a bunch of HP BL25p blades to add to my collection. I am attempting to install Centos4 x86_64 using PXE - the initial PXE DHCP stuff works, and the kernel and initrd are downloaded, but the server then immediately clears the screen and displays: "1706-Smart Array Controller Extended BIOS Data Area Memory Corrupted Array Controller Interrupt 14h BIOS Cannot Continue System Halted" It's pretty obvious what the problem probably is (the kernel nukes some bit of memory that it shouldn't, or that the smart array hasn't properly marked as reserved), but I don't know what to do to fix it. I have also tried: 1) The i386 kernel and initrd images 2) The RedHat AS4 kernel/initrd images 3) The Centos3 i386 kernel and initrd images 4) Downgrading the System ROM BIOS and Smart Array BIOS (as shipped it had the latest versions) to versions up to a year old. 5) Playing with memmap to exclude mem from 610-640K from being used by the kernel. Booting from CD works, but is suboptimal (I have to type the kernel kickstart options, and I don't want to have to do that 16 times, plus I want easy repeatability in future). Google has been fairly silent on the issue. Does anyone have any suggestions for what else I could try/prod/poke?
