Maybe a weird question, maybe just a lack of knowledge on my part (or something I've forgotten over the years), but I'm curious, it's bugging me and I want to understand it 😀
In my 486 DX-33 machine running DOS6.22, I config my CD-ROM drive using VIDECDD.SYS and MSCDEX, and I would regularly get CDR101 errors when trying to "dir". The drive LED wouldn't even blink once, just like it's not even trying.
After some hit and miss investigation, it appears the problem happens when I boot the machine, and directly go to E:, then "dir". If I do a first "dir" while on the C: prompt, then switch to E: and dir, everything works as expected, like doing a "dir" on the HDD first forced a kind of IDE initialization the CD-ROM is not able to do itself, then behaves normally.
Is there anything logical behind this, and does it mean I have something wrongly configured?
I'm using a VLB I/O card with 2 IDE connectors. First IDE has 2 CF/IDE adapters (drives C and D), works fine. Secondary IDE only has the CD-ROM drive as master.
Cheers!
