i have a siemens mobile scenic 710 of 1998. A few days ago i change my harddrive (1,44 GB by 20 GB), bios only detects a drive of 8GB. when a start with MSDOS i can't reach the drive, so i cant install windows98. i only can install windows xp. the drive is in Fat32 format. what can i do to get access to the drive in dos or what can i do to install win98?
