Hi Arkady! The bug submitter for "clear high parts of 32 bit registers on exec" claims to have experienced actual problems because of one program leaving values in registers and another program assuming those parts to be 0. However, he does not tell anything about which program is affected.
If it would be DOS4GW then we would be really motivated :-). > How DOS should deal with third and fourth drives - I don't know, but I > suggest, this is possible only through driver.sys (there you point physical > drive number 0..127, and it traps next logical drive letter). You just said that BIOS would handle it and that equipment list can handle up to four drives as well. So why would we need a driver sys for it? And I do indeed suggest to make driver sys a kernel builtin if we need it at all. > Ie. you offer to integrate help, tutor and training subsystem into > kernel? Currently DOS ignores DOS=UMB statement, if there are no UMBs > available. I think, extra messages like "NO UPPER MEMORY AVAILABLE FOR YOUR > DOS=UMB STATEMENT" makes only uncomfortable noise. This is partially true. Better error messages are sometimes good but a whole tutor system would mean noise. By the way, does the kernel suppress showing more than one UMB-warning if you have more than one DEVICEHIGH/INSTALLHIGH now? Bernd filed a bug report / feature request to suppress the extra noise. > Manifest from QEMM > package offers `Hints' menu, where it offer tips how to optimize the system This reminds me that some QEMM versions spoil APMDOS / ADV:... mode of FDAPM (i.e. it saves no energy if QEMM loaded). If you have QEMM yourself, feel free to test whether your version is affected in combination with your CPU and BIOS. Manifest was a cool piece of software at the time. About bug 1789, kernel confused by PKZIP-builtin format command: I think the LBA-... error message happened at the beginning and the end of the process. But please do read the whole bugzilla entry and contact the bug reporter to learn more, I do not use PKZIP (I use Info-ZIP ZIP / UNZIP).
