Hi, I got some strange problems with DEVLOAD: If I use it to load any of my ramdisks, FreeDOS becomes unable to "cd .." or "cd \", but you can still "cd somewhere" or "cd x:\somewhere\" and do dir to the root directory and similar.
This seems to happen for all sorts of XMS drivers, even in DOSEmu, so it is probably a bug in DEVLOAD or the FreeDOS KERNEL. Please test with some XMS driver and (maybe non-FreeDOS) kernels from your collection. I would really be happy to know whether it is DEVLOAD or rather the kernel which causes this problem. Note that it does NOT happen if you e.g. load xmsdsk as a program from the prompt, only if devload is involved. Looks like xmsdsk is better in self-loading than devload is in loading block drivers. But I have no idea where to start searching, so before this can be discussed on the kernel list or before some bug-hunting for devload can be done, some TEST RESULTS would be really helpful. My test was with the deskwork.de dwdos ramdisk, but all ramdisks seem to be affected. I used a size of 15000k, which should default to 468 clusters fat12, 32kb per cluster, 1 fat, 512 root dir entries. The abovementioned "cd" problems happened in plain DOS, but you get the same problems for diskimage drives in DOSEmu. Lredir drives in DOSEmu just look completely empty after you devload any ramdisk. Any clues or test results on this are very welcome. Thanks! Eric PS: I REALLY hope there will be some test results out there. After that, we can still move the discussion to devel or kernel if people want that. PPS: I found this when experimenting with the new EMM386... It works better but somehow you can still crash AuGoS if you load a ramdisk and use EMM=... option of EMM386...? ------------------------------------------------------- This SF.Net email is sponsored by the 'Do More With Dual!' webinar happening July 14 at 8am PDT/11am EDT.
