Hi there everyone.\n\nI have taken up the project of upgrading the memory in this old Packard\nBell computer (thank you eBay) however, I seemed to run into a problem\nand was wondering what could be the possible solution.\n\nFirst, alittle back info. on the computer. Its a Packard Bell Legend\n836CDT with a 166MHz processor, 72MB memory, ~4.3GB Hard drive. BIOS\nupgraded to Agoura 1.20.\n\nThe machine orginally had 72MB (8MB onboard plus 2x32MB 72-pin 70NS\nSIMMS EDO). I purchased two more similar chips, same specs different\nmanufacture, to bring the system to it's full capacity, 136MB.\nHowever, after installing the chips and turning it on, nothing happens.\nThe hard drive and processor fan power up, however, nothing comes up\non the monitor. There are no beeps...nothing.\n\nAfter searching Google for awhile, I found Ray's Packard Bell website.\nOn the page about my motherboard (PB600) it mentions the following: ".\n.. .I have read that one of the Banks Has a Problem with EDO RAM in some\nPB 600 motherbords." Thinking that this was the problem, I headed over\nto eBay and purchased two 32MB SIMMS that were FPM however, when I put\nthem in, the same problem still occured.\n\nSo, I began to test different combinations, including:\n\n(Orginal)\nBank 2: Two 32MB EDO Chips\nBank 3: Two 32MB EDO Chips\n\nBank 2: Two 32MB EDO Chips\nBank 3: Two 32MB FPM Chips\n\nBank 2: Two 32MB FPM Chips\nBank 3: Two 32MB EDO Chips\n\nbut the same occured. When I put in three chips, in any configuration\nlisted above, the system boots and recognizes 104MB.\n\nAll the above chips are 70ns and I am thinking that maybe this is the\nproblem however, the manual says that the memory must be 70ns or\ngreater.\n\nAnother thing I was thinking was maybe the system will only work with\nFPM. I was thinking about purchasing four 32MB SIMMs FPM 60NS but\nwanted to get some opinions/feedback from other users.\n\nA third thing I was thinking was that perhaps the problem lies with the\nBIOS version. I did find an upgrade for the BIOS and upgraded it\nseveral years ago, however, I did not save the orginal. I have tried\nre-flashing the BIOS but no go. Does anyone have the orginal BIOS\nversion they could send me so I could revert it to its orginal version?\n\nSorry for writing a book; just wanted to get down all the facts.\nThanks in advance.
