Notes
Notes
The 4DMS-HL3G maybe not be wired correctly for L1 write-back support. To fix:
- Add a bodge wire connecting the CACHE# pin on the P24D pinout to the CACHE# pin for the Pentium OverDrive.
- Add a jumper to the first unpopulated jumper immediately underneath JP5 and set this jumper as Closed.
- Set jumpers according to attached picture for Am5x86.
