I tried to insstall RH Linux 5.2 onto 2 PCs with 8MB memoty installed in each/ One of them was 486DX2/66, another - 386DX33 FTP istallation, Boot and supplemental disks were made with updated images. Usually when I boot istallation programm it works until some moment when it starts to reread supplemental diskett (that is inserted in this time). Sounds are like the case of the bad blocks, But the disketts are good (I changed several disks). The moment when the system starts reread the diskett depends on how quick I choose different menus in the installation process. Usually it happen when fdisk starts. It looks like 8MB memory doesnt enough.
This is a memory issue with machines with 8 megs or less that we are working finding a fix for. Until that time, one possible workaround is placing additional memory in the machine you want to install. You then remove the additional after installation. We hope to have a solution for this as soon as possible.
