System Hangs After PCI Device Listing During Windows 95 OSR2 Installation

Hello everyone,

I'm encountering an issue while trying to install Windows 95 OSR2 on my computer and would appreciate any assistance or insights.

CPU: Pentium 166 MMX
Motherboard: QDI P5i430TX
Memory: 32 MB SDRAM
Graphics Card: S3 Virge
Primary Hard Drive: CF card (set as master, and it says "LRG, UDMA 4, 8019MB")
Current OS: MS-DOS 6.22 (boots without issues)

After installing Windows 95 OSR2, the installation process begins normally. However, during the first restart, the system hangs after listing PCI devices, and no further messages appear. Notably, the PCI device listing at the freeze point is identical to the listing displayed when booting successfully into MS-DOS 6.22.

The first time this happened, I didn't realize it was related to the Windows 95 installation. About a month later, I tried restoring the HDD and attempted the installation again and encountered the same issue.

Has anyone experienced a similar problem or have any suggestions on how to resolve this boot hang during the Windows 95 installation process?

Thank you in advance for your help!

I'd try running fdisk /mbr and sys c: before rebooting the first time

Thank you for your response. This suggests that the issue may not be directly related to the Windows 95 system.

I conducted some tests and suspect it might be related to the CF card and 4K alignment. Windows 95 does not boot with an 4k aligned industrial CF card but boots successfully with a consumer CF card. I need to perform additional tests.

After running more tests, I still can't clearly explain why the system boots differently with various CF card types and 4K alignment.

However, using a Windows 95 repair disk to boot and running [sys c:] to fix the boot sector definitely works.
