BIOS and CMOS Error Messages and How to Fix Them
โถ BIOS ROM Checksum error
This error appears when there is a problem with the ROM that stores system information.
It occurs when there is an issue while reading the information stored in CMOS. In this case, enter CMOS SETUP and check whether each setting is configured correctly for the current system state.
After completing the settings, select 'SAVE AND EXIT SETUP' to save the changes.
If the system is old, the ROM itself that stores the BIOS information may be damaged. In that case, it is recommended to have it inspected at a motherboard repair shop or service center.
โถ Press [F1] to continue
This message usually appears when the keyboard or mouse is not connected properly.
Please check whether both devices are connected securely to their connectors.
It is also a good idea to check whether the hard disk information is set correctly in CMOS SETUP.
โถ CMOS memory size mismatch
This error occurs when the system cannot properly recognize the memory (RAM).
When new RAM is added, CMOS usually detects it automatically, but in some cases the correct memory size is reflected only after running CMOS SETUP.
Enter CMOS SETUP, check the settings, and then reboot the system.
โถ NO ROM BASIC
This message appears when an error occurs during booting.
It usually occurs when the system cannot boot from drive A. In this case, you need to insert a bootable floppy disk into drive A or change the boot setting to boot from the hard disk drive.
Similar error messages include 'Diskette Boot Failure' and 'Invalid Boot Diskette'.
โถ CMOS display type mismatch
This error occurs when there is a problem with the graphics-related settings in CMOS.
It happens when the graphics type in the 'Video...' item in CMOS SETUP is not set to EGA/VGA.
Since this is the default setting used by most graphics cards, please make sure to check it.
โถ Cache Memory Bad..
This indicates a problem with the cache memory installed on the motherboard.
Cache memory is used to improve system speed, and on some motherboards, this error may appear if the cache memory fails.
In this case, you can replace the cache memory or try setting the cache memory usage option in CMOS SETUP to 'Disable'.
The same symptom may also appear when cache-related settings such as 'Cache Write' are configured incorrectly, so please check those settings as well.

The "Failed to initialize sound library." Error Appears When Recording Starts
When recording with oCam, sound-related errors may occur. To prevent this, it is important to first check whether sound playback is working properly on your PC. If you try to record on a PC where sound playback is not available, an error is likely to occur. Below is a detailed explanation of how to record with oCam in an environment where sound playback is unavailable and how to configure the settings to avoid errors.
If sound is not playing properly on your PC, you can solve the problem by disabling oCam's system audio recording feature. Please follow the steps below:
1. Launch the oCam main window.
2. In the main window, click the 'Sound' button.
3. When you click it, a pop-up menu will appear, and in most cases the 'Record System Audio' option will be checked by default.
4. Click the 'Record System Audio' item to uncheck it.
With this setting, oCam will not try to record system audio, so you can continue recording without errors even on a PC where sound playback is not available. This setting is especially useful in environments where system audio is not output due to sound driver problems or hardware issues.
Before recording, always check the sound playback status of your PC and apply the setting above if necessary to create a stable recording environment. If you want to resolve the sound playback issue more fundamentally, updating the sound driver or checking the device's sound settings is also a good approach.
