ThinkPad A30 DVD issue

[Cerber4444]

Hello everyone! I've recently installed Windows SP1 on my A30, but its seems that laptop is struggling with it. So I thought that I will Install Windows 2000 than, but suddenly DVD drive doesn't see any disks that I insert in it. It wasn't an issue until now, DVD worked perfectly before and after re-installing a new sistem (both XP). All manipulations I've made was- Installed a XP to have clean system (all drivers was installed right after that), then I've connected HDD to a modern system through IDE to USB dongle to quickly remove all viruses (they was make ThinkPad don't see a USB devices) and copy a bunch of retro software and games. After that, I suppose, it stopped seeing any disks I insert. But something to mention- DVD was working before installing driver, but after installing them I've not tried a DVD drive until yesterday.
I need an advice on how to diagnose and fix this issue. And also- if it will be not fixable, can I just connect ThinkPads HHD through dongle to my modern PC and just install a Windows 2000 like that and make it work on ThinkPad after that?
Thank You for attention.

I do believe you might have a botched chipset driver that's preventing the DVD drive from working properly within Windows, if the DVD drive boots installation media just fine with the F12 boot option.
This is a common issue under Win9x with the default drivers on Banias/Dothan machines like the T4x/R5x, which you have to change the IRQ settings to resolve a hidden resource conflict.
Moreover, check the BIOS settings for the DVD drive speed, set it to Normal option if it's in Silent mode just to exclude compatibility issues with the Silent mode operation.
Also try both Ultrabay slots.

Can you describe it more specific? I don't know a lot about old systems.
