站长 Wengier, thank you for the boot disk you provided. There are the following problems in use:
First, let me tell you the configuration of my old computer:
KT133A (EPOX) + AMD Athlon850 + 40GB (5400 RPM) + 256MB (PC133 SDRAM) + GF2 MX400.
The C drive is 502MB (FAT16) and has DOS 7.10 installed. (Installation method: Use the compressed version of IO.SYS from April 24th, use SYS C:, then copy all the files on the A drive and all the files in the memory virtual disk to the C:\DOS7 directory. In config.sys, only VIDE-CDD.SYS and HIMEM.SYS are loaded. In AUTOEXEC.BAT, only the Chinese and English long filename driver, DOSKEY, and MSCDEX are loaded.) When loading UMBPCI.SYS, the following prompt appears on the screen:
ROM : C000H -CB7FH
EMS : not found
RAM : not found
Error : No upper memory found, RAM was not Loaded
Based on the above error prompt, I did not load UMBPCI.SYS in the CONFIG.SYS of C:.
The more unexpected problem is behind. After I configured DOS 7.10, I then directly installed Windows 2K pro under DOS. smartdrv must be run. The copying files after running winnt in the i386 directory of the CD actually took 40 minutes, which is equivalent to not loading smartdrv. I first thought that smartdrv was not loaded before running winnt. Later, I simply repartitioned the entire hard drive (using GDISK, version: 2003), and reconfigured DOS 7.10 again (that is, re-editing the config.sys and autoexec.bat files). SYS C: still used the boot disk from April 24th. After loading smartdrv again and installing Windows 2K from the CD, the result was the same. The copying time was long, exceeding 40 minutes. According to normal, this copying process should be completed in less than 5 minutes. At first, I suspected that it was the problem of the installation CD. After completing the installation of Windows 2K, when installing Windows XP, I simply copied all the files in the I386 directory to the hard drive for installation.
The command is as follows:
xcopy H: (CD drive letter)\I386\*.* /S /E D:\WINXP
Unexpectedly, the copying file time was also long. At that time, I really got into a fix.
With a resolute heart, I repartitioned the hard drive again and reinstalled the system again. This time, I used the Windows 98 installation CD to boot to pure DOS and used SYS C:, and the rest remained unchanged. As a result, when installing Windows 2K again, it was much faster. The first copying file only took less than 5 minutes and returned to normal. After installation, when installing Windows XP from the CD again, it was also fast and returned to normal.
In the subsequent installation tests, using the previous boot disk made by Wengier (referring to the boot disk without compressing IO.SYS) to install Windows 2K and Windows XP did not have the above errors, but UMBPCI.SYS could not be used on my computer.
Finally, I still thank Wengier for the boot disk. The DOS system I have now, except that MSDOS.SYS, IO.SYS, and COMMAND.COM are provided by the Windows 98 installation CD, many DOS software uses the software in Wengier's boot disk, such as: ATTRIB, SHUTDOWN, FDISK, XMSDSK, etc.
As for whether the above problem is caused by the compressed IO.SYS, I don't know. I raise it in the hope that Wengier's boot disk can be more compatible and stable.
