Let me talk about how it was after trying it out:
The machine I tested it on was P3 500/TNT2 16M/40G hard drive/D-Link 530TX/VIA694X/256M.
The first one I installed was the W98plus1.gho he provided. This system is based on the first edition of Win98. Both hardware and software installation went very smoothly. Internet access at my workplace is shared, so I didn't test using a modem or ADSL dial-up to get online. Since the author optimized the network, the Internet speed was very fast, and the speed of browsing webpages and downloading was simply excellent. The browser used was opera.
As for application software, I tried a slimmed-down edition of office 97, but later found that the WPS.Office.2003.Green.Edition version was the best. This WPS 2003, only 10M in size, can fully support Microsoft's office file formats.
The author had already integrated archive software and image viewer software into it, I just replaced WinRAR with the latest version.
Because I wanted to watch DVDRip movies downloaded from the Internet and run the MAME emulator, I only installed DX8.1.
I installed the NERO5 CD burning software, and CD burning worked too. I tested data CDs and MP3 CDs and both had no problems.
I have to mention the shortcomings of W98plus1. First, Explorer: its address bar can't accept input and can't copy either, which is rather inconvenient. Since the browser used is opera, some websites can't be accessed, which is also inconvenient. When installing the driver for the motherboard's built-in AC97 sound card, I found that only drivers in .inf format could be installed, while WDM format ones could not, so the effect when playing MP3s was really too poor.
There is no "Show Desktop" function, which is also inconvenient.
After that I didn't continue testing the W98plus2 based on the second edition of Win98. Instead, I downloaded 98lite, then installed the second edition of Win98 and began trimming the system manually. Combining it with the advantages of W98plus, I kept the IE-kernel-based Explorer, successfully installed the WDM-format sound card driver, and got proper MP3 playback. Of course, most importantly, I kept the author's network optimizations and disabled the swap file. After slimming down the system, I installed IE6, DX8.1, MyIE0.8, and NERO6. The system size is now 222M. It can very conveniently go online, watch DVDRip, and burn CDs. I didn't slim it down any further.
Oh, and I deleted all the input methods that came with the system and switched to 万能无笔.
But it still has its inconvenient points. Because I often play Stud at the China Game Center, and have to open at least 20 accounts on one machine to collect gold coins, sigh, no way around it, I still have to use Win2003.
