I have a couple of Toshiba laptops 220CS / 470 CDT / 490XCDT and 750 CDT. All of them should support DIMMs EDO 66MHz (as I have checked in the specification). I have one memory stick - Transcend 32M 144P DIMM [C2] - 32MB and it is working... I have however a couple of other memory sticks: - IBM 32 …

Today, I have discovered that the Master/Slave problem is not uniform among all old Toshiba laptops. From my recent experiments: Toshiba 400CDT would accept only ATAPI slave drive Toshiba 430CDT would accept both ATAPI master and ATAPI slave. This is a mess... since 440CDX, 470CDT, 490XCDT, 530CDT …

Is there any list of laptop ATAPI devices with this master/slave switch?

The files are gone but the filenames are still there, hopefully they can correct it and don't just remove the older models altogether. You can use their website to find the filenames for your model, then use this archive.org link to get the files instead: https://web.archive.org/web/*/http://209. …

Yes, seems like Dynabook removed all downloads for the old Toshiba notebooks some months ago. That's really a shame :( I couldn't even find an email address to contact them. I really hate when companies hide themselves in such a way I have written to them using e-mail to Canadian support, but they …

That's great news :) I do think the drives with the switch setting are the easiest option. A note of caution too, if doing the solder CSEL > Master modification - I put the original Toshiba's Teac CD-220EA drive back into the caddy with pin 45 & 47 still connected on the caddy PCB, now the drive …

Good luck with getting your drives working :) With this modification, any drive can be installed into the caddy and should work with all Toshiba laptops with the matching caddy type. Thank you! Your solution works! I have just find-out that one of my LG drives has this switch. It was hidden under …

Maybe there is a whitelist in bios after all. If you upload a dump someone should be able to find it (Im not promising anything). At this moment I do not have such dumps, but I have the BIOS updates from the official Dynabook support (I have downloaded them when they were available). 4750tb72 and …

Update: I have checked what will happen on Toshiba Tecra 750CDT and I get „HDC Error”. After that computer starts but CD-ROM is not detected. From what I have learnt over the Internet, HDC stands for Hard Drive Controler. However, I cannot find what I could do to make these CD-ROMs work/detect.

As a supplement to my initial post. After I install the ATAPI drive that is not detected. Laptop stays a long time on the initial screen: https://www.vogons.org/download/file.php?mode=view&id=173712 Then after a couple of minutes I could enter the bios (if I press ESC-F1) and BIOS settings looks as …

Early Atapi had its struggles https://www.os2museum.com/wp/the-secret-history-of-atapi/, but 20x drive is anything but early. Thank you for this resource. The described ATAPI history is interesting. However it seems that in 1993/1994 the specification was established. My drives from Toshiba laptops …

Hello, this is my first topic started on Vogons, I hope that someone will be able to help me. I have a weird problem. After replacing TEAC CD-220EA, XM-1502B and XM-1602B with more modern ATAPI devices the Toshiba 470cdt/490xcdt/530cdt is not starting. I have tried various more modern drives in …

BTW, the CD-ROM drives I have in my Toshibas that fit the Satellite 4xx series are: XM-1202B - oldest, manufactured November 1995 - special connector, taller than 12.5mm, makes cool sounds. pickup sled rail needed moving/cleaning before it would work reliably XM-1402B - middlest, manufactured …
