DOCUMENT:Q171284 25-MAR-2002 [win95x] TITLE :Problems Enumerating CardBus Devices with No Free IRQs PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER::2,2.1 OPER/SYS: KEYWORDS:kbenv kbhw osr2 win95 kbHardware ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows 95 OEM Service Release, versions 2, 2.1 ------------------------------------------------------------------------------- SYMPTOMS ======== When you are running Windows 95 on a computer with CardBus slots, you may experience the following symptoms: - When multiple PC Cards are installed and the computer is started, Windows may not start and you may receive the following error message: While initializing ... device V86MMGR: Insufficient memory to initialize Windows. - If Windows is running with one PC Card inserted, the computer may become unresponsive for several minutes when you insert another PC Card. When the computer returns from this busy state, Device Manager Reports the new card as disabled because of a resource conflict (code 12). CAUSE ===== These symptoms can occur if there are not enough available IRQ lines for all the installed devices. RESOLUTION ========== To work around this issue, make more IRQ resources available by disabling a device (such as a COM port or LPT port). Such devices can typically be disabled in Device Manager. STATUS ====== This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows. MORE INFORMATION ================ If there are not enough available IRQ lines, there is no configuration that allows all devices to be active without a resource conflict. A device must be removed or disabled to free an IRQ line and allow the remaining devices to be configured successfully.
