The main specifications indicate that the ZR24w only supports 60 Hz signals (59.9 – 60.1 Hz) and "text mode" is listed as 640×480. However, in the list of recognized modes in the monitor's manual (p. 37) all the modes are 60 Hz except for: Preset Pixel Format Horz Freq (kHz) Vert Freq (Hz) 2 720 × 400 31.469 70.087 Given the conflicting ...

This is a consequence of a buggy overflow check. Internally, MS-DOS uses logical block addressing to access file systems. Since version 4.0, MS-DOS uses 32 bits for sector addresses in order to support disks larger than 32 MiB (i.e. than 65536 sectors). To ensure all sectors are addressable with 32 bits, MS-DOS tries to compute the address of the last ...
