Fixes & Enhancements
The following updates were made to the A17 BIOS to create A18:
Issues Fixed:
1. Fixed issue in which a change to the Pointing Device field in System Setup doesn't take effect on a warm reboot.
2. Fixed audio stuttering heard when the fans turn on or off while playing music or videos.
3. Fixed issue seen on systems with more than 256MB RAM and a USB mouse attached in which Win2K won't boot.
4. Fixed issue seen under Win2K in which some DOS applications detect EGA instead of VGA video.
5. Fixed issue in which the system may intermittently fail to detect that a battery is installed.
6. Fixed issue in which some systems may fail to finish booting to WinME, Win2K and WinXP if the system modular bay is empty or contains a 2nd battery.
7. Fixed video corruption seen when entering System Setup with more than 256MB RAM installed.
8. Fixed issue seen under ACPI Operating Systems in which the volume hotkeys do not update the mixer unless the mixer is open or audio is playing.
9. Fixed issue seen under WinXP in which ATAPI drives (CD-ROM, DVD-ROM, ZIP) are not recognized when hot-plugged if one of these drives was previously removed while in Suspend or Hibernate.
10. Fixed issue in which the system may fail to boot to a CardBus NIC.
11. Fixed issue in which booting to a ZIP250 drive may fail on some systems.
12. Fixed issue seen under WinNT 4.0 in which the system may hang when a password-protected 2nd Hard Disk is hot-plugged into a C/Dock or C/Dock II.
13. Fixed issue seen under Win2K in which the system may fail to resume from Suspend if a password is installed in System Setup and the suspend was initiated with a lid-close.
Enhancements:
1. Removed Numlock settings for docked & undocked profiles in System Setup and added a new field called "Enable Keypad". This allow users to more accurately control the behavior of the internal keypad.
2. Updated the ATI VBIOS to version 4.092.
