They have been telling you false stories, AAC has been shipping 512K PB modules for 8 months now. > So, I get the systems back to the office, fire one up, and after all of > the usual BIOS messages, I'm greeted with the message "Pipline Burst Cache"!! :-) > > Can I trust this message?

Most likely. > Taking a look at the module, I see that it bears the label: "CACHE > MODULE CM1 REV 1.3". It has 4 Winbond W25P010AF-8 chips and one ISSI > IS61C256AH-15J chip. Is this the right beastie? Yes, and even the latest revision of the module :-) The W25P010AF-8 chips are 32Kx32 bit PBurst SRAM chips, for 128K bytes of cache each, times 4 of them makes 512K of cache. The IS61C256AH-15J is the tag ram. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
