Warning: irq not configured - Dell Vostro 1510 Laptop

After turning on unit and before the windows logo appears, press F8 repeatedly until a new display appears. Use the arrow key up or down and choose "Last configuration that worked".

If you have a dvd of any other OS .... insert into Drive .... when you turn on have it go to setup ... usually hit F2....
turn on the cd/dvd drive as first drive to load
save
reboot
now your into your machine

you should be able to see all the drives in my computer ..
there are youtube videos for you to change the password now

Sounds like it could be a problem with the hard drive itself.

First thing you should try is booting the laptop with the hard drive removed.

Let me know what happens, you will get an error message (related to the hard drive of course not being installed)

Linux offers various tools. Linux uses ttySx for a serial port device name. For example, COM1 (DOS/Windows name) is ttyS0, COM2 is ttyS1 and so on.
Task: Display Detected System's Serial Support

Simple run dmesg command
$ dmesg ' grep tty
Output:
[ 37.531286] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 37.531841] 00:0b: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 37.532138] 0000:04:00.3: ttyS1 at I/O 0x1020 (irq = 18) is a 16550A setserial command

setserial is a program designed to set and/or report the configuration information associated with a serial port. This information includes what I/O port and IRQ a particular serial port is using, and whether or not the break key should be interpreted as the Secure Attention Key, and so on. Just type the following command:
$ setserial -g /dev/ttyS[0123]
Output:
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 16550A, Port: 0x1020, IRQ: 18 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

setserial with -g option help to find out what physical serial ports your Linux box has.

It seems you have an IRQ conflict. You install a driver and it wants to use an IRQ which is already assigned to a different device. That's why you can start in safe mode because the drivers for your added devices are not loaded.

The computing phrase "interrupt request" (or IRQ) is used to refer to either the act of interrupting the bus lines used to signal an interrupt, or the interrupt input lines on a Programmable Interrupt Controller (PIC). The interrupt request level (IRQL) is the priority of an interrupt request.

In computing, an IRQ conflict is a once common hardware error, received when two devices were trying to use the same interrupt request (or IRQ) to signal an interrupt to the Programmable Interrupt Controller (PIC).

The PIC expects interrupt requests from only one device per line, thus more than one device sending IRQ signals along the same line will generally cause an IRQ conflict that can freeze a computer.

To view your current IRQ assignments you can open Device Manager. Click on START, click on CONTROL PANEL. Click on Performance and Maintenance. Click on System. Click on the Hardware tab. Click the DEVICE MANAGER button. Once you have Device Manager open, select VIEW from the tool-bar menu, and then click Resources by Type. Double click on Interrupt Request (IRQ). If you are experiencing problems with a newly installed/configured piece of hardware and the drivers are installed correctly, then check to see if it has its own IRQ channel.

To change an IRQ setting follow these steps:
-Right click on the device in the list (see above), and then select properties.
-Click the Resources tab.
-Remove the tick from the Use automatic settings option.
-Select a non-conflicting configuration from the pull down box.
-Click OK.

this error says IRQ are in conflict as this means pci card is in hardware conflict with other devices. please check in device manager with device it is in conflict and update drivers

Hi,

Normally conflicts would be with the IRQs assigned to a device. Some methods of resolving conflicts are:
1. relocating the device to another slot;
2. manually configuring the IRQs in the CMOS/BIOS setup;
3. manually configuring the IRQs in Device Manager.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Can u be please clear about your problem. Why do you want to change the IRQ numbers .

You can go to BIOS and PCI/PNP configuration and change IRQ mode AUTO to Manual and assign how ever you like

Good Luck

there is no PCI lock on any retail boards. But there are IRQ sharings and conflicts. Set IRQ to auto, if not, then manualy and if so, then disable a few things, just to free up some IRQs. All depends on the board, best is to consult the manual for the IRQ sharing table and work with that. (disable one SERIAL, IDE port or USB port if you need an extra IRQ) Also check for onboard equivalent to the card you are adding, disable the onboard part...
