These are the known considerations for using your ThinkPad T23 system with Microsoft Windows 98:

• Screen expansion is not supported for DVD playback to external TV at 800 x 600, 256, or 16-bit color mode.
• In systems with Windows 98 installed, when a wireless LAN adapter PC card is installed, the system requires a longer time to boot from a power off condition. Approximately 150 seconds boot time is to be expected. Normal boot times without a wireless PC card installed are approximately 70 to 110 seconds, depending on specific configurations. The time to resume from suspend or hibernate is not affected by the wireless LAN card.
