I'm only grasping at straws here, but I hope that it is somehow possible on this machine? From: http://support.intel.com/support/processors/pentiumiii/xeon/esma.htm <<...OLE_Obj...>> Pentium(R) III Xeon(tm) processors Extended Server Memory Architecture Full 36-bit addressing allows enterprise applications to transcend the traditional 4GB (32-bit) memory barrier by adding 4-additional address bits. PSE36 (Page size extensions) adds 4 additional address lines to the current 32 bit address. As each bit is added, the cacheability range doubles: 32 bits= 4 GB 32 + 1 = 8 GB 32 + 1 + 1 = 16 GB 32 + 1 + 1 + 1 = 32 32 + 1 + 1 + 1 + 1 = 64 GB The additional headroom allows: Greater than 4-gigabytes of cacheable system memory ********************************************************************* Gabriel Leen Tel: 00353 61 20 2677 PEI Technologies Fax: 00353 61 33 4925 Foundation Building E-mail: gabriel.leen@ul.ie University of Limerick Limerick Ireland -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
