Re: [Freedos-kernel] Kernel changes

You mean a FreeDOS 1.1 BASE ISO image? That would be nice, but you can of course use many already pre-packaged updated packages from the fdupdate repository and also the updated installer from Jim for that... There is another problem, though: People why try to download a current kernel end up e.g. on fdos.org which is long dead, but used to contain an automated regular build of the kernel and a minimalistic boot floppy image containing that. Maybe the tradition of having daily builds somewhere could be resurrected, for those who cannot or do not want to compile kernels from the subversion repository manually. This would also be nice for tasks like binary search for when things in a regression bug broke and/or got fixed, etc :-) I do plan on restoring fdos.org, currently the [old] content is still available at fdos.info (e.g. wiki.fdos.info, help.fdos.info, and www.fdos.info). FYI: fdos.info is just a new domain name that is mapped to the same content fdos.org used to point to. fdos.org points to a new hosted virtual computer - early last November I had started migrating my data from the old site to the new one, but all my computers were stolen - hopefully in month I'll finally have a replacement.

When using Jack Ellis' RDISK (RAM drive) it won't find the volume Hallelu-Jah in 2039 whereas 2038 works fine. (If you really really want, I can upload my test floppy image where I discovered the problem.) In particular, I originally used 2038pre when making the floppy disk for testing, and when 2038 came out I upgraded. And then when 2039 came out, I figured I should upgrade again but didn't test again until recently. And at startup it immediately tries to jump to RAM disk for my purposes, but definitely a regression since it doesn't find it anymore. I finally had a closer look. What happens is that the int21/11 input pattern of finddisk gets uppercased to HALLELU-JAH, and then case-sensitively compared to the directory entries on the RAM drive. So it doesn't find it. This is compatible with MSDOS, where finddisk doesn't find the RAM disk either. (It's very strange to have a mixed case label as that doesn't match with short-file-name FAT). Older versions of the FreeDOS kernel (=2038) did not compare (ignored) the name for the volume label: it was returned no matter which pattern was given to int21/11 (and 4e). That's why there is %define BUGGY_FCB 1 in finddisk.asm. The correct DOS-independent fix would be to change finddisk to search for the volume label with .???, and then compare the result with the search term.
