JUMP directly here to the LAST EVOLUTIONS on this topic.
From what I have read there are some risks if you don't know what you are doing.
This is how I plan to do.
1-FDISK, originaly, doesn't support large drives. So, first of all, format your new large HD from an existing windows platform.
That can be done from w98 installed on a small HD and using a windows based disk-formating application. The new HD would be installed, of course, as Primary Slave (not as Primary Master) for this operation.
The catch is that you need another physical drive with W98 installed on it to format the new drive because you cannot format a drive Windows is running from even if you do another partition on this drive.
2-How to format? If you installed the right patch to allow w98 to fully use large HD (link) there should be no problem for formatting the whole disc.
However native w98 Scandisk and Disk Defragmenter will crash or corrupt the datas on large partitions unless you updated these application from a fix found on MDGx update thread. But if you forget to do so before defragmenting your partition you will corrupt the datas and may lose everything on it.
So IMO it's preferable to partiton the large drive into several partition of less than 137 Gb (125 GiB).
3-How to install from that?
Shut down the computer.
Swap the HD's in the case, setting the new HD as Primary Master (don't forget to adjust the jumpers). Insert a bootable floppy disk and run the installation from there using basic Dos commands.
4-Once w98 is installed, immediately apply the Break-137Gb-barrier patch (and the 512Mb-Memory-barrier fix at the same time).
As I'v never done it, I'm not sure how the w98 installation will react on the large drive since the patch cannot be applied before the installation. Theoricaly there is no problem until you fill the drive beyond the 137 Gb barrier.
But several partitions could already consist of elementary datas beyond that limit and therefore be erased or corrupted - I don't know.
Please help me if you have experience in this matter.
