|So it's a SATA cdrom but a regular IDE hard drive? I don't think you can boot from a sata cdrom and install 98 as you would with a regular atapi cdrom. That's because the PC will reboot a couple times during the install and since 98 has no SATA support, the cdrom will no longer be seen. So with a SATA cdrom I think I'd copy the WIN98 folder from the cd to the hard drive and run the installation from the hard drive.|
You'd need a bootdisk with a SATA cdrom driver to start things. GCDROM.SYS is a dos SATA cdrom driver and should work. Just add gcdrom.sys to the bootdisk and edit config.sys to load it instead of oakcdrom.sys. The link I have for gcdrom.sys is dead but a google search should turn up a download site.
Once you run the bootdisk and the cdrom is identified, partition and format the drive (if necessary) and copy the system files to the hard drive with the SYS command. Then create a WIN98 directory on the drive and copy the contents of the win98 directory on the cd to the win98 directory on the hard drive. Then reboot from the hard drive and start the installation from the dos prompt with C:\WIN98\SETUP.
Once installed, 98 still won't see the sata cdrom (unless there's 98 sata drivers I'm not aware of) but with gcdrom.sys you can probably use it in msdos compatibility mode. And as the link in sdfox's post shows, if this is part of a system with newer hardware you may have problems finding 98 drivers for a lot of the other stuff too.
