Gelip Posted January 29, 2022 Posted January 29, 2022 (edited) When I needed an ExpressCard for my laptop, I found i-tec EXRS232 WinDbg works with this card if we modify the kdcom.dll file by inserting the I/O address 3000 of the card in place of the port address, e.g. COM1 03F8 ExpressCard i-tec EXRS232, chip Oxford, PCI Vendor:Device 1415:c120 This card only has I/O addresses and works with the modified kdcom.dll The card is attached directly to the PCI Express Root bus: 03:00.0 Serial controller [0700]: Oxford Semiconductor Ltd Device [1415:c120] (prog-if 02 [16550]) Subsystem: Oxford Semiconductor Ltd Device [1415:c120] Flags: bus master, fast devsel, latency 0, IRQ 17 I/O ports at 3000 [size=8] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Legacy Endpoint, MSI 00 Capabilities: [100] Device Serial Number 00-30-e0-11-11-00-01-20 Capabilities: [110] Power Budgeting <?> Kernel driver in use: serial Now I am looking for an RS-232 to PCIe card with which to do the same. I have already purchased two other PCIe cards but the kdcom.dll modification trick does not work PCIe card No.1: Sunrich I-350 PCI-E 1S, chip OXPCIe952, PCI Vendor:Device 1415:c138 This card is attached directly to the PCI Express Root bus but has no I/O addresses only MMIO (Memory at): 03:00.0 Serial controller [0700]: Oxford Semiconductor Ltd Device [1415:c138] (prog-if 02 [16550]) Subsystem: Oxford Semiconductor Ltd Device [1415:c138] Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f0400000 (32-bit, non-prefetchable) [size=16K] Memory at f0200000 (32-bit, non-prefetchable) [size=2M] Memory at f0000000 (32-bit, non-prefetchable) [size=2M] Capabilities: [40] Power Management version 3 Capabilities: [70] Express Endpoint, MSI 00 Capabilities: [b0] MSI-X: Enable- Count=16 Masked- Capabilities: [100] Device Serial Number 00-30-e0-11-11-00-01-30 Capabilities: [110] Power Budgeting <?> Kernel driver in use: serial PCIe card No.2: Sunix SER5427A, chip SUN1989, PCI Vendor:Device 1fd4:1999 This card only has I/O addresses but does not work with the modified kdcom.dll.

infuscomus Posted January 30, 2022 Posted January 30, 2022 @Gelip I recall @Dietmar said he found one that works for XP. Quote
Gelip Posted January 30, 2022 Author Posted January 30, 2022 @infuscomus It works but only in the early starting phase and only with modified NTLDR_DBG. I wrote to @Dietmar PM to share data of your cards in this topic but wrote that there is no time. I am looking for such a PCie card that works with modified kdcom.dll like my ExpressCard I collect information on how these cards work and I know that: there are cards with PCI-to-PCI bridge or without there are Memory-Mapped I/O (MMIO), Port-Mapped I/O (PMIO) or Mixed MMIO + PMIO e.g. --> CH3825SP 03:00.0 Serial controller: Device 1c00:3253 (rev 10) (prog-if 05 [16850]) Subsystem: Device 1c00:3253 Flags: fast devsel, IRQ 17 I/O ports at e000 [size=256] Memory at f0100000 (32-bit, prefetchable) [size=32K] I/O ports at e100 [size=4] Expansion ROM at f7d00000 [disabled] [size=32K] Capabilities: <access denied> Probably needs a card that does not have a PCI bridge and only has an Port-Mapped I/O (PMIO) Quote
infuscomus Posted January 30, 2022 Posted January 30, 2022 @Gelip I can build a kdcom.dll from source code if you think that'll help for this. Quote

As for PMIO addresses, I know in what offsets to change them in kdcom.dll without compilation in a regular hex editor. Maybe you could add another function, e.g. MMIO address? Quote
Gelip Posted January 30, 2022 Author Posted January 30, 2022 I am very curious why the modified kdcom.dll works with my ExpressCard and not with PCIe cards Quote
Dietmar Posted January 30, 2022 Posted January 30, 2022 (edited) @Gelip Make a try with freeldr from Reactos. You also can use Windbg via Lan from @Mov AX, 0xDEAD it works in most cases and is ultrafast Dietmar Bootfiles https://ufile.io/byie80ou XPviaFREELDRorNTLDR.pdf Edited January 30, 2022 by Dietmar Quote
Gelip Posted January 30, 2022 Author Posted January 30, 2022 @Dietmar I am trying to use freeldr flash drive to run WinXP from NTFS partition but I have hive error. Can freeldr boot WinXP from NTFS or FAT32 only? Quote
Gelip Posted January 30, 2022 Author Posted January 30, 2022 11 hours ago, Dietmar said: You also can use Windbg via Lan from The point is KDNET ? - It's only for WinXP 32-bit? Quote
Dietmar Posted January 30, 2022 Posted January 30, 2022 @Gelip Yes, until now it is only for 32 bit, XP SP3 and Win2003. https://github.com/MovAX0xDEAD/KDNET But maybe, that @Mov AX, 0xDEAD already has make the files for Windbg for 64 bit Dietmar Quote
Gelip Posted January 30, 2022 Author Posted January 30, 2022 @Dietmar Is the kdnet.dll file in the WindbgFiles.rar archive (#2633 Win-Raid post) already made by xdelta3.exe? WindbgFiles.rar Quote
Dietmar Posted January 31, 2022 Posted January 31, 2022 (edited) @Gelip Look at the date, when kdnet.dll was changed. I did it on Dienstag, 8. Oktober 2019, 12:15:39 Dietmar PS: The kdnet.dll in this post is from 2014, so it is original file from win8.1 . Edited January 31, 2022 by Dietmar Quote
infuscomus Posted January 31, 2022 Posted January 31, 2022 @Gelip I found this one that doesn't have a bridge chip. https://www.startech.com/en-au/cards-adapters/pex2s553 Quote
Gelip Posted January 31, 2022 Author Posted January 31, 2022 @infuscomus Yes, I have already searched for information on many different cards and found this PEX2S553 but the price is too high so it is out of the question. Besides, I already have 3 different cards and I don't want to buy more if I don't know if it will work. I found one that has "native" in the description - Sunix SER6427A With high reliable SUNIX SUN2212 native PCI Express 16C950 UART controller. The photo does not show that it has a bridge, only a SUN2212 chip: but there is also the question of how this card is addressed - Memory-Mapped I/O (MMIO), Port-Mapped I/O (PMIO) or Mixed MMIO + PMIO ????

Gelip Posted January 31, 2022 Author Posted January 31, 2022 @Dietmar Wow, KDNET works with WinXP 32-bit In Boot.ini, only one line is enough: C:\WINDOWS="KDNET Force IP" /noexecute=optin /fastdetect /DEBUG /DEBUGPORT=NET /HOST_IP=192.168.5.1 /HOST_PORT=50000 /ENCRYPTION_KEY=make.winxp.great.again /CPUFREQ=3000 /TARGET_IP=192.168.5.2 Tested with a laptop with a LAN card integrated Intel. @Mov AX, 0xDEAD Can I use the kdnet_delta.bin file to create kdnet.dll x64-bit and debug WinXP 64-bit?

Gelip Posted January 31, 2022 Author Posted January 31, 2022 @Dietmar Your card does not work with kdcom.dll probably because it is addressed both with MMIO and PMIO. Can you place a screenshot from Device Manager - View -> Devices by connection - Is the card connected directly to PCI Express Root or with a bridge? - see my screenshots in first post. Thx. Quote

Dietmar Posted January 31, 2022 Posted January 31, 2022 (edited) @Gelip This card Lindy 2S 16C950 is also connected via PCI bridge, but shown as normal COM3 and COM4 port. I think, that this bridge is needed, because card sits in a PCIe slot. The COM 2 port is the onboard COM connector. It is connected via PCI-Standard Isa bridge This is the only card, where in Flags: not "Busmaster" is listed, only fast devsel and IRQ. As far as I remember, this card also does not work with Windbg, only some success with freeldr (Fat32) and ntldr_debug Dietmar Edited January 31, 2022 by Dietmar Quote
Gelip Posted January 31, 2022 Author Posted January 31, 2022 (edited) @Dietmar Is the card driver to oxserleg.inf? Is in the Device Manager files serenum.sys and serial.sys from Microsoft? Edited February 6, 2022 by Gelip Quote
