Free Conventional Memory (Bytes)
| | MS-DOS 6.2 | PTS-DOS 6.6 |
| mode | | |
| 1 | not supported | 650.176 |
| 2 | 637.728 | 643.392 |
| 3 | 620.912 | 641.712 |
| 4 | 634.240 | 649.392 |
| 5 | 593.168 | 586.336 |
Modes:
- 1 - Windows incompatible
- 2 - Windows fully compatible
- 3 - Windows fully compatible when Share, Fastopen (3 disks), Loadfix, Keyb,
Disp, ANSI and extended floppy formats support are loaded
- 4 - Windows fully compatible with UMB
- 5 - Windows fully compatible with disk compression loaded
Notes:
- Using HIMEM or HIMEM386 (PTS) only
- In mode 3 MS DOS used 800.COM by Alberto Pasquale (PTS-DOS
supports all nonstandard floppy formats itself)
- In mode 4. PTS uses QEMM 7.03 by Quarterdeck
- Tested on 386DX-40, 4, 210
Disk Compression Driver:
| MS-DOS 6.2 | PTS-DOS 6.6 |
| compression ratio | 1.6 | 1.9 |
Host disk space is 10 Mb. Only files from Windows For Workgroups 3.11
[12.819 Kb]) are on compressed disk.
Some other features:
| MS-DOS 6.2 | PTS-DOS 6.6 |
| ROMable | - | +(128 Kb) |
| Coexistence with other DOS on one disk |
- | + |
| Nonstandard floppy format support |
- | + |
| Total size on disk | approx. 4 Mb | 1.2 MB |
Speed test:
| Test ID | MS-DOS 6.2 | PTS-DOS 6.6 |
| 1. | 1 min 14 sec | 1 min 00 sec |
| 2. | 16 sec | 9 sec |
Tests:
- Copying file group with XCOPY (Windows for Workgroups 3.11
with subdirectories, approximately 27 Mb) from HDD to HDD.
- Copying of a large file (8190 Kb) from HDD to HDD.
(All these tests are performed on 80486DX50 with IDE HDD avg. seek 7 ms)
