Hi,\nI've a HP Kayak XW/450 W3 with 512 MB RAM (4 memory modules 128MB\nECC PC100) and two PIII/600MHz. It works fine - with some little\nproblems:\n\n1. My BIOS version is HK.11.09 from June, 10th 1999. With this I have\na problem: I can't come into Setup with the F2 key, when I press the\nkey, the start procedure runs till the Setup has to come, but then the\nscreen is black and nothing more happened. I only can press\nCtrl+Alt+Del to restart. A second and third BIOS-Update doesn't\neffect.\nThe Helpdesk from HP can't do anything for me, they say that I have to\nmake a 'bios crisis recovery', after this a CMOS-Clear. I did it step\nby step with a manual from the Helpdesk, but it doesn't solve this\nproblem.\n\n2. I want to upgrade to 1 GB with 4 modules 256MB ECC PC133 reg.\nThese modules aren't HP-certified but made by Infineon. They are\ncompatible with a fsb of 100 MHz, I tested it in my computer at home.\nThey also are completely o.k., the BIOS counts to 1023.\nMy problem is, that at boot time, when I press Esc, I can see the BIOS\nchecking\nthe memory, but only up to 511. The MaxiLife LCD display on front of\nthe station finds four dimms of 128MB each. The Kayak started without\nany problems the OS and works fine, but only with 512 MB RAM.\nThe Helpdesk from HP say that I have to take HP-certified memory with\nan fsb of 100 MHz, but I think that's not the right way, because the\nmodules are compatible with 100 MHz (I mailed to Infineon!).\n\nHas anyone an idea?
