Let me guess, a CDD461 or CDD462 on a CM-153 interface card ? I looked at those on Google images and it didn't look like them. The front was significantly bigger than the CD tray and the only button was a (large) eject button. I forget how I came across the drive. I think it was bundled with one of …

Won't that cause disk corruption issues when switching between MS-DOS and Windows(using Akt-Tab)? If a disk write/read gets broken up and Windows(because it gets control) is switched in and changes things on the hard disk, the MS-DOS app won't know and the both of them might corrupt when reading/ …

I'll add, if driver+mscdex work, that will be a way to at least make it accessible in Windows until you find another solution. I once had one of those Philips external drives with a proprietary ISA controller card that I used this way.

I don't have answers but I'm curious whether an atapi CD driver and mscdex work in DOS mode? I thought the whole point of IDE compatbility mode was to be, well, IDE compatible. So you'd think it would at least work slowly under Windows. Maybe windows has a whitelist of pci ids or something and it …

If you're going to put in an ISA sound card, I'd go ahead and narrow down and say it will be DOS/98 based. It's DOS games where having a true Sound Blaster compatible (with working ISA DMA) is helpful as XP games will use Windows drivers and therefore be neutral to what card you actually have. A …

As far as HD disks being recognized, the /dev/fd0 device node is supposed to autodetect disks. There are other …

Debug will read from stdin if you want to do it that way. I'm surprised no one has chimed in about this though, you'd think if all Toshibas of this model worked this way it would be widely known.

Yes, weird. I wonder if the BIOS settings are stored in the boot sector rather than in CMOS or something. DEBUG also has an e command you can use to overwrite things in memory. You could try to use that to write an F8 at 40:00 and an 03 at 40:01 and then exit and run msd. Even if this works, it's …

I got a retail Sound Blaster kit around 1999 or so from a big-box store. It was supposed to be a combo of a PnP Sound Blaster 16 ISA card, and a 48x IDE CD-ROM drive. Inside was a 52x CD-ROM drive and a note explaining that it was faster. I can't find any traces of this kit online from searching …

I was in elementary school and bought an IBM PS/2 30-286 at a yard sale for like $25 or so. Learned a lot of DOS on it, plus it was the first machine I had access to where I could "format c:" and reinstall as often as I wanted as part of learning.

I mean the i/o port in addition to IRQ. Try this, both with the original hdd and the replacement one. Run the DOS debug command at the - prompt type: d 40:00 The first two bytes dumped should be F8 03. To get out of the - prompt just type q It will be interesting if the result differs depending on …

Could still be the belt slipping allowing it to open close the tray but not to fully load the mechanism (raising the laser spindle assembly into position). Try operating the mechanism manually or slamming the tray shut with some enthusiasm in the hope that the inertia completes the loading movement …

Thanks everyone. I just got an eBay drive that wouldn't open. Unfortunately, I didn't test whether it could read CDs otherwise prior to working on the belt... I did the degrease + hot water trick to the belt on the drive and it now opens and closes on its own. However, when I put a disc in, it …

When it successfully detects the serial port, does it say what IRQ and I/O port? This is just speculation but I wonder if part of the configuration that normally goes in the BIOS is actually on the HD, or alternatively, if whatever is on the old HD is filling in some info in RAM that DOS uses to …

This sounds like a bad cable to me. I have seen many monitors where the cable has got damaged where it enters the monitor, if you wiggle the cable can you get proper colors back ? Moving the cable around seemed to be correlated with the flickering at first, but it doesn't do anything now. I wonder …

Thanks for all the replies.

First post in a long time. Anyone found any solutions to old CD-ROM drives that seem like they lose the strength to open on their own? That is, you push the eject button and it feebly tries (and fails) to open. There is no disc inside so it's not a jam. You can use a paper clip to get it opened but …
