The AMD K6-2+ don't run the i686 version?

Don't think cmov is supported, but I could be wrong. I know the installer installs the i586 kernel, and I know that the nahant beta would not install. Following is /proc/cpuinfo for the box in question. Note that it is not a K6/2+ (which has L2 cache on die, like the K6/3, just less cache, along with other highly desirable features), but a straight, 300MHz K6/2.

Hmmm, doesn't list cmov in the flags. In contrast, my Pentium M laptop: [lowen@localhost ~]$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 9 model name : Intel(R) Pentium(R) M processor 1700MHz stepping : 5 cpu MHz : 599.650 cache size : 1024 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr mce cx8 mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe est tm2 bogomips : 1185.43

Lists cmov in the flags.

I bought eight of these boxes in one lot; they are Agilent OC-12 ATMprobes stripped of their OC-12 sniffer cardset (the sniffer cards have more CPU than the motherboard; twin StrongARM's plus some FPGA logic plus an i960 on a PCI dual card and an ISA card (the ISA card used only for power, and it contains that actual OC-12 PHY's (622 S/UNI PMC chips and glue to the twin StrongARM card; each StrongARM has, I think, 256MB of RAM, where the K6 was only given 128MB). I paid $20 per box. Serial console by default; they do have a keyboard port up front hidden behind a panel, but no VGA. Four PCI's and three ISA slots, and a peculiar ATX-connectored open frame power supply. One usable IDE channel is available, on which is hung a single 4.3GB HD, and internally there is a Hitachi CV 8MB CFA drive (on the secondary channel, but set as the primary boot drive). BIOS is Phoenix, and has serial port redirection. Manufacturer string in the BIOS is 'Banner 0.12'.

So, no, i686 doesn't work.

Now, for the acid test for CentOS 4's i586 support; I have a dual Pentium 133 server on which to test, including the nasty DAC960 RAID and four Adaptec EISA SCSI adapters (for an array of CD-ROMs in a LUN-expander library; over 100 CD-ROM drives on on box). If it will boot on frankenbox, it'll boot anywhere :-). I'm not sure what I last ran on the box; might have been Red Hat 8.0 or so.
