I just bought a new motherboard (alladin chipset) and cpu (AMD K6-2 300), and plugged in my old HDD and cd-rom into it. I formatted and re-installed windows 95, and everything seemed to be fine. I installed all the relevant drivers and again everything was fine. Then I noticed that, on one boot I had no cd-rom in explorer or in system. I rebooted and the cd-rom re-appeared, and then worked fine. This has happened a few times now, the bios always detects the cd-rom but then sometimes win95 seems to ignore it. I installed the latest driver (hitachi 7730 4x cd-rom), but the problem remains. I never had this problem with my old m/board and the same version of win95, although that board was faulty in other departments.
Rebooting always seems to sort out the problem, but its a little bit tedious. Any ideas?

Cheers,
Adam

Sounds like your IDE drivers may not be quite right in Windows. Did the motherboard come with Bus Master drivers on a disk or CD?

I installed the bus master drivers off the provided CD but the problem existed before and afterwards. I did however notice one problem while fiddling with it last night. The CD-ROM has a jumper to specify master, slave or CSEL operation, but I hadn't put a jumper on any of them (in my setup it should be a slave to the HDD, as the bios seemed to recognize) - maybe this confuses the computer.

That is possible - you should have it jumpered as slave. You don't need to change the hard drive though.

Seems to be working properly now. Thanks for the help.

If the trouble comes back just add a new post.
