I don't seen an OS noted so for DOS and up to Windows ME you want to stick to 64GB and smaller drives.
And without any indication of 48 BIT LBA SUPPORT the max I'd use on this machine is 127GB and smaller.
Also, how did you solve the P4 overheat crash issue on this one?
What hard drives are compatible with a Dell 8200 Inspiron laptop?
The one I currently have is a Hitachi Travelstar 30GB 4200RPM ATA/IDE
The processor is a Pentium 4 mobile.
