I hope it isn't wrong place we443y ask. I want to install windows 98 to my old 166MHz computer. When i try to install then it says that windows setup requires 'largest executable files to run'. Then i bypassed memory checking but it still says that i don't have any free memory for install. Yesterday i connected old hd as a slave in my newer computer. It didn't work at first but then i changed the drive letter and i don't know what i did after that. Anyway it started to work and i formated it. I can save and copy files to 2,36Gb drive. But when i put it back to an old computer as a master then it can only read the contents. It says - free memory 0. When i connect old hd as a master to my newer computer then it says the same. My english is not perfect but i hope that you guys understand what problem i have. Is that someting with partitions? ------- i have compaq deskpro 2000 and i cant enter to bios. I know that compaq bios uses a small space of hd for setupfiles and diagnostic but i dont know how do i fix the problem. ------ I found that old HD is NTFS filesystem i need to change it to FAT32. Will it help?
