The parity circuit is responsible for generating and checking the parity bit on the system memory when parity checking is used. This circuitry is not working properly.
This code usually means a problem with either the system memory or the motherboard.
you can try swap the memory location
If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.
If you have more than one stick of memory try removing all but one stick of memory and boot the computer. If this does not resolve the issue try removing that stick of memory and try one of the other sticks of memory.
According to the error details in your posting, the error appears after the mouse has been initialized…
I’m not quite sure if an connected USB mouse may cause this error but try to disconnect all the connected devices and try to power up the unit once again…
The error is produced by an hardware device/part malfunction… while booting, the POST (power on self-test) is executed. If POST cannot be passed due to the hardware problems, the BIOS produce a beep code.
If the notebook would still beep even if the external devices have been disconnected, you should start to check the memory modules…
In worst case you will need to ask an Toshiba ASP technician for an hardware check…. It could be possible that your motherboard needs to be replaced.
This error means that there is a problem with an PCI device 01 on the motherboard.
Not quite sure what device could be but I read some interesting news on other webpages.
Someone could solve this booting the notebook with an ejected/opened CD/DVD drive.
Not sure if an CD/DVD drive could cause this issue but try to boot the unit with ejected ODD.
But in worst case I don’t see any other solution as to ask an technician for hardware check.
