Hi,
I'm testing 2 DDR from Samsung on EPIA-M, M368L1713DTL-CB0 and M368L1624DTL-CB0. Both of them are DDR266 128MB. The main different is M368L1713DTL-CB0 has 8x16MB IC's and M368L1624DTL-CB0 has 4x32MB IC's. So far, LinuxBIOS can boot flawlessly with M368L1713DTL-CB0. However, it fails when running ram test. Here is the log

BTW, normal bios doesn't have this problem. And I have also compared settings between regular and LinuxBIOS bios, even double check with DDR init sequence. I haven't found anything strange yet. Have any seen this kind of strange behavior?
